PULSE WIDTH MODULATION (PWM)
OUTPUT CIRCUIT
The 3886 group has two PWM output circuits, PWM0 and PWM1,
with 14-bit resolution respectively. These can operate indepen-
dently. When the oscillation frequency XIN is 10 MHz, the
minimum resolution bit width is 200 ns and the cycle period is
3276.8
s. The PWM timing generator supplies a PWM control
signal based on a signal that is the frequency of the XIN clock.

The following explanation assumes f(XIN) = 8 MHz.
