Product Dependencies
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.
The TC is clocked through the Power Management Controller (PMC), thus the programmer must first configure the
PMC to enable the Timer Counter clock.
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.
