DESCRIPTION

Port 2. 8-bit open-drain bidirectional port with alternative functions.

P2.0/TPWM is the output for the 14-bit high precision PWM.

P2.1/PWM0 to P2.7/PWM6 are the outputs for the 6-bit PWMs 0 to 6.

Port 3. 8-bit open-drain bidirectional port with alternative functions.

P3.0/ADC0 to P3.3/ADC3 are the inputs for the software ADC facility.

P3.4/PWM7 is the output for the 6-bit PWM7.

Digital ground

Port 0. 8-bit open-drain bidirectional port.

P0.5 and P0.6 have 10 mA current sinking capability for direct drive of LEDs.

Digital ground.
