PRELIMINARY
Notice: This s not a final specification.
Some parametric imits are subject to change.
Pulse Width Modulation (PWM)
The 38B5 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 of this data sheet assumes X
IN
= 4 MHz.
