DECFSZ
Decrement f, Skip if 0
Syntax:
DECFSZ f {,d {,a}}
Operands:
0
f 255
d
[0,1]
a
[0,1]
Operation:
(f) – 1 dest,
skip if result = 0
Status Affected:
None
Encoding:
0010
11da
ffff
Description:
The contents of register ‘f’ are
decremented. If ‘d’ is ‘0’, the result is
placed in W. If ‘d’ is ‘1’, the result is
placed back in register ‘f’ (default).
If the result is ‘0’, the next instruction
which is already fetched is discarded
and a NOP is executed instead, making
it a two-cycle instruction.
If ‘a’ is ‘0’, the Access Bank is selected.
If ‘a’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f
95 (5Fh). See
Literal Offset Mode” for details.
