Subtract Literal from FSR
SUBFSR f, k
0 ≤ k ≤ 63
f ∈ [ 0, 1, 2 ]
FSR(f) – k → FSRf
None
The 6-bit literal ‘k’ is subtracted from
the contents of the FSR specified by
‘f’.

Q1
Subtract Literal from FSR2 and Return
SUBULNK k
0 ≤ k ≤ 63
FSR2 – k → FSR2
(TOS) → PC
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.
