5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Programmable Timer)
5.10 Programmable Timer
5.10.1 Configuration of programmable timer
The S1C88832/88862 has two built-in 8-bit
programmable timer systems (timer 0 and timer 1).
Timer 0 and timer 1 are composed of 8-bit
presettable down counters and they can be used as
8-bit
× 2 channels or 16-bit × 1 channel programma-
ble timer. They also have an event counter function
and a pulse width measurement function using the
K10 input port terminal.
Figure 5.10.1.1 shows the configuration of the
programmable timer.
Programmable setting of the transfer rate is possi-
ble, due to the fact that the programmable timer
underflow signal can be used as a synchronous
clock for the serial interface.
Furthermore, this halved underflow signal (TOUT)
can also be output externally from the R27 output
port terminal. Furthermore, the R26 output port
terminal can be used to output the TOUT signal
(TOUT inverted signal) by mask option.
5.10.2 Count operation and
setting basic mode
Here we will explain the basic operation and
setting of the programmable timer.
s Setting of initial value and counting down
The timers 0 and 1 each have a down counter and
reload data register.
The reload data registers RLD00–RLD07 (timer 0)
and RLD10–RLD17 (timer 1) are registers that set
the initial value of the counter.
By writing "1" to the preset control bit PSET0 (timer
0) or PSET1 (timer 1), the down counter loads the
initial value set in the reload register RLD.
Therefore, down-counting is executed from the
stored initial value according to the input clock.
