3.6 Timers
The TMP90C400 incorporates four 8-bit timers.
The four 8-bit timers can operate independently, and also
function as two 16-bit timers through cascade connection.
Timer 2 is provided with 8-bit timer/event counter and can
be used as 16-bit counter by connecting with 8-bit counter or
timer 3.
8-bit interval timer mode (4 timers)
16-bit interval timer mode (2 timers)
- Possible arrangements: 8-bit x 2 and 16-bit x 1
8-bit programmable square wave (pulse) generation (PPG:
variable duty with variable cycle) mode (Timers 1, 0)
8-bit pulse width modulation (PWM: variable duty with con-
stant cycle) mode (Timer 1)
8-bit event counter mode (Timer 2)
16-bit event counter mode (Timer 2, 3)
Software counter latch function (Timer 2, 3)
3.6.1 8-bit Timers
The TMP90C400 incorporates four 8-bit interval timers (Tim-
ers 0, 1, 2 and 3), each of which can be operated indepen-
dently. The cascade connection of Timer 0 and 1, or Timer 2
and 3 allows these timers used as 16-bit internal timers.
Figure 3.6 (1) shows a block diagram of the 8-bit timers
(Timer 0 and Timer 1).
Figure 3.6 (2) shows a block diagram of the 8-bit timer/
event counters (Timer 2 and Timer 3).
Each interval timer is composed of an 8-bit up-counter, an
8-bit timer register, with a timer tlip-flop (TFF1) provided to
each pair of Timer 0/1.
Internal clocks (T1, T16 and T256) for the input clock
sources to the interval timers are generated by the 9-bit prescaler
shown in Figure 3.6 (3).
Their operating modes of the 8-bit timers and flip-flops
are controlled by 4 control registers (TCLK, TFFCR, TMOD
and TRUN).
