Description
25
TI
HSI.1
---
High Speed Input Module, input pin 1.
Setting IOC0.2 = 1 enables pin 25 as an HSI input, and allows
events on this pin to be loaded into the HSI FIFO.
TI
T2CLK
HSO.4
---
---
Timer 2 Clock.
Setting IOC0.7 = 1 and IOC3.0 = 0 enables pin 25 to function as
the Timer 2 clock source.
26
TO
High Speed Output Module, output pin 4. This pin can simulta-
neously operate in the HSI and HSO modes of operation. As a
result, this pin acts as an output that the HSI monitors.
Setting IOC1.4 = 1 enables the HSO.4 function of pin 26.
TI
HSI.2
---
High Speed Input Module, input pin 2. This pin can simulta-
neously operate in the HSI and HSO modes of operation. As a
result, this pin can monitor events on the HSO.
Setting IOC0.4 = 1 enables pin 26 as an HSI input pin, and
allows events on this pin to be loaded into the HSI FIFO.
27
TO
TI
HSO.5
HSI.3
---
---
High Speed Output Module, output pin 5. This pin can simulta-
neously operate in the HSI and HSO modes of operation. As a
result, this pin acts as an output that the HSI monitors.
Setting IOC1.6 = 1 enables the HSO.5 function of pin 27.
High Speed Input Module, input pin 3. This pin can simulta-
neously operate in the HSI and HSO modes of operation. As a
result, this pin can monitor events on the HSO.
Setting IOC0.6 = 1 enables pin 27 as an HSI input pin, and
allows events on this pin to be loaded into the HSI FIFO.

HSO.0
HSO.1
---
---
High Speed Output Module, output pin 0. The HSO.0 pin is a
dedicated output for the HSO module.
High Speed Output Module, output pin 1. The HSO.1 pin is a
dedicated output for the HSO module.
