CHAPTER 8 8-BIT TIMER/EVENT COUNTERS 2 TO 5
8.1
Functional Overview
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.
