TMP96C141AF
3.8 8-Bit PWM Timer
The TMP96C141AF/TMP96CM40F/TMP96PM40F has two
built-in 8-bit PWM timers (timers 2 and 3).
They have two operating modes.
• 8-bit PWM (pulse width modulation: variable duty at fixed
interval) output mode
• 8-bit interval timer mode

Figure 3.8 (1) is a block diagram of 8-bit PWM timer (tim-
ers 2 and 3).
PWM timers consist of an 8-bit up-counter, 8-bit com-
parator, and 8-bit timer register. Two timer flip-flops (TFF2 for
timer 2 and TFF3 for timer 3) are provided.
Input clocks φ P1, φ P4, and φ P16 for the PWM timers can
be obtained using the built-in prescaler.
PWM timer operating mode and timer flip-flops are con-
trolled by four control registers (P0MOD, P1MOD, PFFCR, and
TRUN).
