4.18.2

Signal Description

4.18.2.1

Overview

The TIM16B4C module is internally connected to the PTB (IOC0, IOC1, IOC2) and to the Rx signal as specified in Section 4.17,

“General Purpose I/O - PTB[0…2]" (IOC3).

4.18.2.2

Detailed Signal Descriptions

4.18.2.2.1

IOC3 – Input Capture and Output Compare Channel 3

NOTE

Since the Rx signal is only available as an input, using the output compare feature for this

channel would have no effect.

This pin serves as input capture or output compare for channel 3 and is internally connected to the Rx signal as specified in

Section 4.17.2, “Alternative SCI / LIN Functionality".

4.18.2.2.2

IOC2 – Input Capture and Output Compare Channel 2

This pin serves as an input capture or output compare for channel 2 and can be routed to the PTB2 general purpose I/O.

4.18.2.2.3

IOC1 – Input Capture and Output Compare Channel 1

This pin serves as an input capture or output compare for channel 1 and can be routed to the PTB1 general purpose I/O.

4.18.2.2.4

IOC0 – Input Capture and Output Compare Channel 0

NOTE

For the description of interrupts see Section 4.18.6, “Interrupts".

This pin serves as an input capture or output compare for channel 0 and can be routed to the PTB0 general purpose I/O.
