DESCRIPTION

PWM9/PATOUT/P3.1 41 PWM9 to PWM0: 8-bit Pulse Width Modulation outputs 9 to 0. Pin 41 and 42 can

PWM8/CLAMP/P3.0

PWM7/P2.7

42 also be used as the output pin of the test pattern display PATOUT and clamping out

1

signal CLAMP respectively; PATOUT and CLAMP always have the higher priority.
