PWM output mode
(1) 8-bit timer counter mode (discrete mode)
The timer can be used for the following functions in this mode.
8-bit resolution interval timer
8-bit resolution square wave output (timer 40 only)
(2) 16-bit timer counter mode (cascade connection mode)
These timers can be used for 16-bit timer operations via a cascade connection.
The timer can be used for the following functions in this mode.
16-bit resolution interval timer
16-bit resolution square wave output
(3) Carrier generator mode
In this mode the carrier clock generated by timer 40 is output in the cycle set by timer 30.
(4) PWM output mode
In this mode, a pulse with an arbitrary duty ratio, which is set by timer 40, is output.
