10.3 TPM Block Diagram
SoC Guide — MC9S08RG60/D Rev 1.10
The TPM uses one input/output (I/O) pin per channel, TPM1CHn where x is the TPM number (for
example, 1 or 2) and 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 Pins and Connections section for more information).
Figure 10-2 shows the structure of a TPM. Some MCUs include more than one TPM, with various
numbers of channels.
