PULSE WIDTH MODULATION (PWM)
OUTPUT CIRCUIT
The 3885 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 8 MHz, the minimum
Fig. 23 PWM block diagram (PWM0)
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 following explanation assumes f(XIN) = 8 MHz.
