TABLE 1:
The core registers in the enhanced PIC12/16 are the
same as the legacy registers with the addition of a
second FSR/INDF, the BSR and mapping the W
register in WREG. The IRP, RP0 and RP1 bits are no
longer present in the STATUS because the BSR is now
available and the FSRs are now 16 bits wide.
TABLE 2:
These instructions were designed to fit inside the
“holes” in the existing 14-bit instruction word. By fitting
the existing memory design, the cost of the enhanced
devices was kept similar to the existing PIC12/16,
simplifying the decision to use the new features.
