16.2 FUNCTIONAL DESCRIPTION OF 10-BIT IH-PWM

16.2.1 PWM
The 10-bit PWM circuit has the following components:

10-bit comparator circuit

10-bit counter

10-bit reference data registers (PWMDATAH/L)

10-bit preset PWM data registers (PWMPDATAH/L)

PWM output pins (P0.3/PWM)
16.2.2 PWM CLOCK RATE
The timing characteristic of PWM output is based on the f
clock value is determined by setting PWMCON.6–.7.
