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.
