any selected frequency, and for PWM output. Two 8-bit timer/event counters can be used as one 16-bit timer/event
counter.
7.2 Function of 8-Bit Timer/Event Counter
138
An 8-bit timer/event counter can be used as an interval timer, external event counter, to output a square wave with
The 8-bit timer/event counters (50, 51, and 52) have the following two modes.
• Mode in which an 8-bit timer/event counter is used alone (single mode)
• Mode in which two or more 8-bit timer/event counters are connected in cascade (16-bit resolution: cascade mode)
These two modes are explained below.
(1) Mode in which an 8-bit timer/event counter is used alone (single mode)
(2) Mode in which TM50 and TM51, or TM51 and TM52 are connected in cascade (16-bit resolution: cascade
In this mode, the 8-bit timer/event counter can be used for the following functions.
• Interval timer
• External event counter
• Square-wave output
• PWM output
mode)
By connecting 8-bit timer/event counters in cascade, they can be used as a 16-bit timer/event counter.
In the cascade mode, the 8-bit timer/event counters can be used for the following functions.
• 16-bit resolution interval timer
• 16-bit resolution external event counter
• 16-bit resolution square-wave output
