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 Interrupt Controller (IC). Handling the TC interrupt requires
programming the IC before configuring the TC.

The TC has trigger/capture inputs internally connected to the PWM. Refer to 

 and to the product Pulse Width Modulation (PWM) implementation.

The TC has the FAULT output internally connected to the fault input of PWM. Refer to 

 and to the product Pulse Width Modulation (PWM) implementation.

The nine channels of the Timer Counter are independent and identical in operation except when quadrature
decoder is enabled. The registers for channel programming are listed in 

.

Each channel is organized around a 32-bit counter. The value of the counter is incremented at each positive edge
of the selected clock. When the counter has reached the value 2

32

-1 and passes to zero, an overflow occurs and

the COVFS bit in the TC Status Register (TC_SR) is set.

The current value of the counter is accessible in real time by reading the TC Counter Value Register (TC_CV). The
counter can be reset by a trigger. In this case, the counter value passes to zero on the next valid edge of the
selected clock.
