5.1 Multiple CAP and MAT pins
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally-supplied clock, and can optionally generate interrupts or perform other actions
at specified timer values, based on four match registers. It also includes four capture
inputs to trap the timer value when an input signal transitions, optionally generating an
interrupt.
Table 24–545
Table 545. Timer/Counter pin description
Software can select multiple pins for most of the CAP or MAT functions in the Pin Select
registers, which are described in
MAT output, all such pins are driven identically. When more than one pin is selected for a
CAP input, the pin with the lowest port number is used.
Each Timer/Counter contains the registers shown in
the data stored in used bits only; it does not include reserved bits content). More detailed
descriptions follow.

Description
Capture Signals- A transition on a capture pin can be configured to load one
of the Capture Registers with the value in the Timer Counter and optionally
generate an interrupt. Capture functionality can be selected from a number
of pins. When more than one pin is selected for a Capture input on a single
TIMER0/1 channel, the pin with the lowest Port number is used
Timer/Counter block can select a capture signal as a clock source instead of
the PCLK derived clock. For more details see
Register (T[0/1/2/3]CTCR - 0xE000 4070, 0xE000 8070, 0xE007 0070,
0xE007 4070)” on page
External Match Output 0/1- When a match register 0/1 (MR3:0) equals the
timer counter (TC) this output can either toggle, go low, go high, or do
nothing. The External Match Register (EMR) controls the functionality of this
output. Match Output functionality can be selected on a number of pins in
parallel.
