Pulse Width Modulators (PWMs)
11.4.2 PWMB Control Register
Advance Information

NOTE:
Address:
PSA1B, PSA0B, and PSB3B PSB0B — PWM Clock Rate Bits
Any non-zero value of PSA1B PSA0B forces PB5 to the PWMB output
state. If PSA1B PSA0B = 00, PB5 is determined by the port B data and
data direction registers as described in
Input/Output
Reset:
Read:
Write:
These bits select the input clock rate for PWMB and determine the
period as shown in
as the corresponding bits in the PWMA control register except they
affect the PWMB output pin.
