Q1
Subtract Literal from FSR2 and Return
SUBULNK k
0  k  63
FSR2 – k  FSR2,
(TOS)  PC
None
The 6-bit literal ‘k’ is subtracted from the
contents of the FSR2. A RETURN is then
executed by loading the PC with the
TOS.
The instruction takes two cycles to
execute; a NOP is performed during the
second cycle.
This may be thought of as a special case
of the SUBFSR instruction, where f = 3
(binary ‘ 11 ’); it operates only on FSR2.
