Triple Timer Module Programming Model

9.4.6Timer Compare Register (TCPR)

The TCPR is a 24-bit read/write register that contains the value to be compared to the counter value. These two values are compared every timer clock after TCSR[TE] is set. When the values match, the timer compare flag bit is set and an interrupt is generated if interrupts are enabled (that is, the timer compare interrupt enable bit in the TCSR is set). The TCPR is ignored in measurement modes.

9.4.7Timer Count Register (TCR)

The TCR is a 24-bit read-only register. In timer and watchdog modes, the contents of the counter can be read at any time from the TCR register. In measurement modes, the TCR is loaded with the current value of the counter on the appropriate edge of the input signal, and its value can be read to determine the width, period, or delay of the leading edge of the input signal. When the timer is in measurement mode, the TIO signal is used for the input signal.
