TC Description
16-bit Counter
Clock Selection
Table 31-2.
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 Timer Counter clocks are frozen during debug operation, unless the OCD system keeps
peripherals running in debug operation.
The Timer Counter clock is generated by the power manager. Before using the TC, the program-
mer must ensure that the TC clock is enabled in the power manager.
The TC has an interrupt line connected to the interrupt controller. Handling the TC interrupt
requires programming the interrupt controller before configuring the TC.
The three channels of the Timer Counter are independent and identical in operation. The regis-
ters for channel programming are listed in
Each channel is organized around a 16-bit counter. The value of the counter is incremented at
each positive edge of the selected clock. When the counter has reached the value 0xFFFF and
passes to 0x0000, an overflow occurs and the COVFS bit in SR (Status Register) is set.
The current value of the counter is accessible in real time by reading the Counter Value Regis-
ter, CV. The counter can be reset by a trigger. In this case, the counter value passes to 0x0000
on the next valid edge of the selected clock.
At block level, input clock signals of each channel can either be connected to the external inputs
TCLK0, TCLK1 or TCLK2, or be connected to the configurable I/O signals TIOA0, TIOA1 or
TIOA2 for chaining by programming the BMR (Block Mode). See
