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