Answer 1

ADC (256GB106)	This peripheral library module provides: Up to 16 analog input pins, designated AN0 through AN15, on the 10-bit A/D converter, depending on the particular device pinout. Two analog input pins for external voltage reference connections. Voltage reference inputs that may be shared with other analog input pins.
Analog Comparator (256GB106)	This peripheral library module: Provides two ranges of output voltage, each with 16 distinct levels. Can come from either VDD and VSS, or the external VREF+ and VREF-. Note: The settling time of the comparator voltage reference must be considered when changing the CVREF output.
Capture Input (256GB106)	This peripheral library module: Capture a timer value from one of two selectable time bases upon an event on an input pin. Has a four-level FIFO buffer. The number of capture events required to generate a CPU interrupt can be selected by the user. Has multiple operating modes which are selected via the ICxCON register.
Compare/PWM Output (256GB106)	This peripheral library module: Is used to generate a single output pulse. Can be used to configure the module for the generation of a continuous stream of output pulses or for PWM operations. Provides a double buffer for the PWM duty cycle and is essential for glitchless PWM operation.
CRC (256GB106)	This peripheral library module: Implements a software configurable CRC generator. Incorporates a FIFO that is 8 deep when PLEN (PLEN<3:0>) > 7, and 16 deep otherwise.
CTMU (256GB106)	This peripheral library module: Functions to configure CTMU. Function to control current. Provides macros to control edge sequence and to configure interrupt. Incorporates a FIFO that is 8 deep when PLEN (PLEN<3:0>) > 7, and 16 deep otherwise.
I2C (256GB106)	This peripheral library module: Supports BYTE and WORD transmission and reception. Incorporates multiple BYTE and WORD transmission and reception in a single function call. Provides simple functions to read from and write to the buffers. Provides simple interface macros to enable/disable interrupts.
IOPorts (256GB106)	For this peripheral library: A parallel I/O port that shares a pin with a peripheral is, in general, subservient to the peripheral. When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled.
PMP (256GB106)	This peripheral library module: Is a parallel 8-bit I/O module. PMP stands for Parallel Master Port module. Is specifically designed to communicate with a wide variety of parallel devices, such as communications peripherals, LCDs, external memory devices and microcontrollers. Is highly configurable, since the interface to parallel peripherals varies significantly.
PowerManagement (256GB106)	This peripheral library module: Implements Power Management features of the device. Provides functions to switch between operating frequency. Provides macros to detect the reset source and to enter the device into IDLE/Sleep modes.
PPS (256GB106)	This peripheral library module provides: Assign given pin as input or output pin. Provides macros to Lock and unlock the PPS.
RTCC (256GB106)	This peripheral library module: Provides a Real-Time Clock and Calendar (RTCC) function. Is intended for applications where accurate time must be maintained for extended periods of time with minimum to no intervention from the CPU. Is optimized for low-power usage in order to provide extended battery lifetime while keeping track of time.
SPI (256GB106)	This peripheral library module: Supports BYTE and WORD transmission and reception. Incorporates multiple BYTE and WORD transmission and reception in a single function call. Provides simple functions to read from and write to the buffers. Provides simple interface macros to enable/disable interrupts.
Timers (256GB106)	For this peripheral library module: The Timer1 module is a 16-bit timer , Timer2/3 and Timer4/5 modules are 32-bit timers, which can also be configured as four independent 16-bit timers with selectable operating modes. Timer 1 operates in CPU Idle modes and Sleep modes. Individually, Timer2/3 and Timer4/5 of the 16-bit timers can function as synchronous timers or counters. ADC Event Trigger is implemented only with Timer5.
UART (256GB106)	This peripheral library module: Supports BYTE and WORD transmission and reception. Incorporates multiple BYTE and WORD transmission and reception in a single function call. Provides simple functions to read from and write to the buffers. Provides simple interface macros to enable/disable interrupts.
WDT (256GB106)	This peripheral library module: Provides function to enable Watch Dog Timer.
SRAM (256GB106)	This peripheral library module: Function for byte ,page and sequential Read and Writes The code uses the on-chip SPI hardware peripheral to communicate with the serial SRAM.
