The TPM uses one input/output (I/O) pin per channel, TPM1CHn where n is the channel number (for
example, 0–4). The TPM shares its I/O pins with general-purpose I/O port pins (refer to the
Connections
include more than one TPM, with various numbers of channels.
The central component of the TPM is the 16-bit counter that can operate as a free-running counter, a
modulo counter, or an up-/down-counter when the TPM is configured for center-aligned PWM. The TPM
counter (when operating in normal up-counting mode) provides the timing reference for the input capture,
