PULSE WIDTH MODULATION (PWM)
The 38B4 group has a PWM function with a 14-bit resolution. When
the oscillation frequency XIN is 4 MHz, the minimum resolution bit
width is 250 ns and the cycle period is 4096 s. The PWM timing
generator supplies a PWM control signal based on a signal that is
the frequency of the XIN clock.
The explanation in the rest assumes XIN = 4 MHz.
