38.3 Pin Name List
38.4 Product Dependencies
38.4.1 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.
38.4.2 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.
38.4.3 Interrupt
The TC has an interrupt line connected to the Advanced Interrupt Controller (AIC). Handling the
TC interrupt requires programming the AIC before configuring the TC.
