Timer Pulse-Width Modulator (TPMV2)
B.1
The TPM uses one input/output (I/O) pin per channel, TPMxCHn 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
B.2
The TPM has the following features:

Each TPM may be configured for buffered, center-aligned pulse-width modulation (CPWM) on all
channels
Clock sources independently selectable per TPM (multiple TPMs device)
Selectable clock sources (device dependent): bus clock, fixed system clock, external pin
Clock prescaler taps for divide by 1, 2, 4, 8, 16, 32, 64, or 128
16-bit free-running or up/down (CPWM) count operation
16-bit modulus register to control counter range
Timer system enable
One interrupt per channel plus a terminal count interrupt for each TPM module (multiple TPMs
device)
Channel features:
— Each channel may be input capture, output compare, or buffered edge-aligned PWM
— Rising-edge, falling-edge, or any-edge input capture trigger
— Set, clear, or toggle output compare action
— Selectable polarity on PWM outputs

shows the structure of a TPM. Some MCUs include more than one TPM, with various numbers
This chapter refers to S08TPM version 2, which applies to the 3M05C and
older mask sets of this device. 0M74K and newer mask set devices use
S08TPM version 3. If your device uses mask 0M74K or newer, please refer
to
for information pertaining to that module.
