(3) Multiple PWM (Pulse Width Modulation) output
By extending the PWM function and using one master channel and two or more slave channels, up to seven types
of PWM signals that have a specific period and a specified duty factor can be generated.

(4) Remote control output function
The pairings of channels 2 and 3 and channels 6 and 7 are used to output the PWM signal. The PWM signal
output from channel 3 is used as a mask waves, the PWM signal output from channel 7 is used as a carrier waves,
and the logical products of these signals are output as remote control output.
