Port 1 Pin 1. A quasi-bidirectional port pin that is read and writ-
ten at location 0Fh of HWindow 0.
Port 1 Pin 2. A quasi-bidirectional port pin that is read and writ-
ten at location 0Fh of HWindow 0.
Port 1 Pin 3. A quasi-bidirectional port pin that is read and writ-
ten at location 0Fh of HWindow 0.
Setting IOC3.2 = 0 enables the P1.3 function of pin 22.
TUO
PWM1
---
Pulse Width Modulator (PWM) Output 1. The output signal
will be a waveform whose duty cycle is programmed by the
PWM1_CONTROL register, and the frequency is selected by
IOC2.2.
Setting IOC3.2 = 1 enables the PWM1 function of pin 22.

TUO
P1.4
---
---
Port 1 Pin 4. A quasi-bidirectional port pin that is read and writ-
ten at location 0Fh of HWindow 0.
Setting IOC3.3 = 0 enables the P1.4 function of pin 23.
PWM2
Pulse Width Modulator (PWM) Output 2. The output signal
will be a waveform whose duty cycle is programmed by the
PWM2_CONTROL register, and the frequency is selected by
IOC2.2.
Setting IOC3.3 = 1 enables the PWM2 function of pin 23.
24
TI
TI
HSI.0
---
High Speed Input Module, input pin 0. Unless masked, a rising
edge on this input will generate the HSI.0 Pin interrupt (INT04,
2008h). Assert the HSI.0 pin for at least 2 state times to ensure
acknowledgment by the interrupt controller.
Setting IOC0.0 = 1 enables pin 24 as an HSI input, and allows
events on this pin to be loaded into the HSI FIFO.
T2RST
High
Timer 2 Reset. A rising edge on the T2RST pin resets Timer 2.
To enable the T2RST function of pin 24, set IOC0.3 = 1 and
IOC0.5 = 1.
