29.3.1 TPM_EXTCLK — TPM External Clock
The rising edge of the external input signal is used to increment the TPM counter if
selected by CMOD[1:0] bits in the SC register. This input signal must be less than half of
the TPM counter clock frequency. The TPM counter prescaler selection and settings are
also used when an external input is selected.
29.3.2 TPM_CHn — TPM Channel (n) I/O Pin
Each TPM channel can be configured to operate either as input or output. The direction
associated with each channel, input or output, is selected according to the mode assigned
for that channel.
29.4 Memory Map and Register Definition
This section provides a detailed description of all TPM registers.
Attempting to access a reserved register location in the TPM memory map will generate a
bus error.
