37.4 Pin Name List
37.5 Product Dependencies
37.5.1 I/O Lines
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines. The programmer must
first program the PIO controllers to assign the TC pins to their peripheral functions.
37.5.2 Power Management
The TC is clocked through the Power Management Controller (PMC), thus the programmer must first configure the PMC
to enable the Timer Counter clock.
37.5.3 Interrupt
The TC has an interrupt line connected to the Interrupt Controller (IC). Handling the TC interrupt requires programming
the IC before configuring the TC.
