8-Bit Timers

The TMP93CS40 and S41 contain two 8-bit timers (Timers 0 and 1), each of which can be

operated independently. The cascade connection also allows these timers to be used together as

a 16-bit timer. The following four operating modes are supported for the 8-bit timers:

•

8-bit interval timer mode (2 timers)

•

16-bit interval timer mode (1 timer)

•

8-bit programmable square wave pulse generation (PPG: Variable duty with variable

cycle) output mode (1 timer)

•

8-bit pulse width modulation (PWM: Variable duty with constant cycle) output mode (1

timer)

Figure 3.7.1 shows the block diagram of the 8-bit timers (Timer 0 and timer 1).

Each timer consists of an 8-bit up counter, 8-bit comparator, and 8-bit timer register. Besides,

one timer flip-flop (TFF1) is provided for the pair consisting of timer 0 and timer 1.

Among the input clock sources for the timers, the internal clocks of

φT1, φT4, φT16, and φT256

are obtained from the 9-bit prescaler shown in Figure 3.7.2.

The operation modes and timer flip-flops of the 8-bit timers are controlled by the three control

registers TMOD, TFFCR, and TRUN.
