TMP90CM38
3.6 Timers
The TMP90CM38 contains four 8-bit timers (timers 0, 1, 2 and
3), each of which can be operated independently. The cas-
cade connection allows these timers to be used as 16-bit tim-
ers.
The following four operating modes are provided for the 8-
bit timers.
8-bit interval timer mode (4 timers)
16-bit interval timer mode (2 timers)
8-bit programmable square wave pulse generation (PPG:
variable duty with variable cycle) output mode (2 timers)
8-bit pulse width modulation (PWM: variable duty with con-
stant cycle) output mode (2 timers
The upper two can be combined (two 8-bit timers and
one 16-bit timer).
Figure 3.6 (1) shows the block diagram of 8-bit timer
(timer 0 and timer 1).
8-bit timer (timer 2, 3) are connected to the external clock pin
TI2 in the timer 2 up counter input clock.
Other timer 2 and timer 3 have the same circuit configura-
tion as timer 0 and timer 1. Each interval consists of an 8-bit
up-counter, 8-bit comparator, and 8-bit timer register. Besides,
one timer flip-flop (TFF1 or TFF3) is provided for each pair of
timer 0 and timer 1 as well as timer 2 and timer 3.
Among the input clock sources for the interval timers, the
internal clocks of T1, T4, T16, and T256 are obtained
from the 9-bit prescaler shown in Figure 3.6 (2).
The operation modes and timer flip-flops of the 8-bit timer
are controlled by five control registers T01MOD, T23MOD,
TFFCR, TRUN, and TRDC.
