8-Bit Timer
independently. The cascade connection also allows these timers to be used together as two
16-bit timers. The following four operating modes are supported for the 8-bit timers:
•
•
•
•
one timer flip-flop (TFF1) is provided for the pair consisting of timer 0 and timer 1, and TFF3 is
provided for the pair consisting of timer 2 and timer 3.
are obtained from the 9-bit prescaler shown in Figure 3.7.3.
registers T10MOD, T32MOD, TFFCR, TRUN, and TRDC.
The TMP93CS20 contains four 8-bit timers (timers 0 to 3), each of which can be operated
Figure 3.7.1 shows the block diagram of the 8-bit timers (timer 0 and timer 1).
Figure 3.7.2 shows that of the 8-bit timers (timer 2 and timer 3).
Each timer consists of an 8-bit up counter, 8-bit comparator and 8-bit timer register. Besides,
Among the input clock sources for the timers, the internal clocks of φT1, φT4, φT16, and φT256
The operation modes and timer flip-flops of the 8-bit timers are controlled by the five control
