14.3.2 Function of output select blocks
The output select blocks select whether the P1B2/PWM1 and P1B1/PWM0 pins are used as general-purpose
output port pins or D/A converter pins.
This selection can be made by the PWM1SEL and PWM0SEL flags of the PWM mode select register. Each
pin can be set in the port mode or D/A converter mode independently.
The P0C1/PWM1 and P0C0/PWM0 pins are N-ch open-drain output pins and must be connected with an
external pull-up resistor.
The configuration and function of the PWM mode select register is shown in Figure 14-3.
