How many bits are required to address the program memory of PIC16F887? What is PCLATH? For PC absolute addressing, describe how to write assembly program to jump to code located in a different program memory page.

Expert Solution

8000bits(8Kb) are required to address the program memory of PIC16F887. The fig below represents program mapping of PIC16F887.

PCLATH Registers: The size of the program memory of the PIC16F887 is 8K. Therefore, it has 8192 locations for program storing. For this reason the program counter must be 13-bits wide (2^13 = 8192). In order that the contents of some location may be changed in software during operation, its address must be accessible through some SFR. Since all SFRs are 8-bits wide, this register is “artificially” created by dividing its 13 bits into two independent registers: PCLATH and PCL.

13 Register File Structure in PIC 16F887

Eight lower bits (the low byte) come from the PCL register which is readable and writable, whereas five upper bits coming from the PCLATH register are writable only.
The PCLATH register is cleared on any reset.
