TMP90C051
When disabling the timer
Writing “0” to bit <PA3> of address #FFE7H disables
the timer, disables carry operations and prevents
misoperation due to the CLOCK HOLD circuit.
The CLOCK HOLD circuit holds once only the 1-sec-
ond carry signal generated by the divider while the
timer is disabled, corrects the time by outputting the carry
signal to the timer after the timer is enabled, and con-
tinues operating
.
If the timer disable continues for
longer than one second, however, the timer is delayed.
Caution must be exercised here in that the TMP90C051F
system power supply is halted while the timer is dis-
abled. In this case, the timer remains stopped and the
time is delayed; therefore, when a system power-down
is detected while the timer is disabled, always return to
timer enable and then set BAKEN (Back Up Enable) to “0”.
