Operation:
00h
WDT,
0 WDT postscaler,
1 TO,
0 PD
Status Affected:
TO, PD
Encoding:
0000
0011
Description:
The Power-Down status bit (PD) is
cleared. The Time-out status bit (TO)
is set. The Watchdog Timer and its
postscaler are cleared.
The processor is put into Sleep mode
with the oscillator stopped.

If WDT causes wake-up, this bit is cleared.
SUBFWB
Subtract f from W with Borrow
Syntax:
SUBFWB
f {,d {,a}}
Operands:
0
f 255
d
[0,1]
a
[0,1]
Operation:
(W) – (f) – (C)
dest
Status Affected:
N, OV, C, DC, Z
Encoding:
0101
01da
ffff
Description:
Subtract register ‘f’ and Carry flag
(borrow) from W (2’s complement
method). If ‘d’ is ‘0’, the result is stored in
W. If ‘d’ is ‘1’, the result is stored in
register ‘f’ (default).
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
