TSTFSZ
Test f, Skip if 0
Syntax:
TSTFSZ f {,a}
Operands:
0
f 255
a
[0,1]
Operation:
skip if f = 0
Status Affected:
None
Encoding:
0110
011a
ffff
Description:
If ‘f’ = 0, the next instruction fetched
during the current instruction execution
is discarded and a NOP is executed,
making this a two-cycle instruction.
If ‘a(chǎn)’ is ‘0’, the Access Bank is selected.
If ‘a(chǎn)’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a(chǎn)’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f
95 (5Fh). See
