Design Tips
Question 1:
Answer 1:
1.
2.
Question 2:
Answer 2:
if the STATUS register is the destination for an instruction that affects the Z, DC, or C bits, the
write to these bits is disabled. These bits are set or cleared based on device logic. Therefore, to
modify bits in the STATUS register it is recommended to use the BCF and BSF instructions.
The destination of the instruction may be specifying the W register (d = 0) instead of the
file register (d = 1).
The register bank select bits (RP1:RP0 or IRP) may not be properly selected. Also if inter-
rupts are used, the register bank select bits may not be properly restored when exiting the
interrupt handler.
My program algorithm does not seem to function correctly.
I cannot seem to modify the STATUS register flags.
