5.1.2 Multi-channel linkage operation function
The multi-channel linkage operation function is a combination of the master channel (the reference timer
for the main control period) and the slave channel (the timer that operates in accordance with the master
channel).
The multi-channel linkage operation function can be used as the following mode.
(1) Single trigger pulse output
Use 2 channels in pairs to generate a single-trigger pulse that arbitrarily sets the output timing and pulse
width.

(2) PWM (Pulse Width Modulation) output
Use 2 channels in pairs to generate pulses that can set the period and duty cycle arbitrarily.

(3) Multiple PWM (Pulse Width Modulation) outputs
Up to 3 arbitrary duty cycle PWM signals can be generated in a fixed period by extending the PWM
function and using 1 master channel and multiple slave channels.
