8-Bit Timer/Event Counters 2 to 5 (TM2 to TM5)

7.2.1

Function outline

8-bit timer/event counter n has the following two modes (n = 2 to 5).
• Mode using 8-bit timer/event counter alone (individual mode)
• Mode using cascade connection (16-bit resolution: cascade connection mode)
These two modes are described below.
(1) Mode using 8-bit timer/event counter alone (individual mode)
8-bit timer/event counter n operates as an 8-bit timer/event counter.
The following functions can be used.
• Interval timer
• External event counter
• Square wave output
• PWM output
(2) Mode using cascade connection (16-bit resolution: cascade connection mode)
TM2 and TM3, and TM4 and TM5 can be used as 16-bit timer/event counters when they are connected in
cascade. The following functions can be used.
• Interval timer with 16-bit resolution
• External event counter with 16-bit resolution
• Square wave output with 16-bit resolution
The block diagram of 8-bit timer/event counter n is shown next.
