If C/T
executed during the next machine cycle and lasts for
the next 5 machine cycles. The results of this reset are
identical to those of a hardware reset. The internal
RAM is not affected and the special register assume
the values shown in Table 3.

As there are no precautions for protecting bit WDT
from spurious writing in the IOCON register, special
care must be taken when writing the program. In
particular, the user should use the IOCON register bit
handling instructions :
–
SETB and CLR x
in preference to the byte handling instructions :
–
MOV IOCON, # XXH, ORL IOCON, #XXH,
–
ANL IOCON, #XXH
External Counting in Power-down Mode
(PD = PCON.1 = 1)
In the power-down mode, the oscillator is turned off
and the 83C154’s activity is frozen. However, if an
external clock is connected to one of the two inputs,
T1/T0, TIMER/COUNTERS 0 and 1 can continue to
operate.
In this case, counting becomes asychronous and the
maximum, admissible frequency of the signal is
OSC : 24.
The overflow of either counter TF0 or TF1 causes an
interrupt to be serviced or forces a reset if the counter
is in the WATCHDOG MODE (T32 = ICON.7 = 1).
