Timer/Pulse-Width Modulator (S08TPMV2)
10.1.2 Features
The TPM has the following features:
⢠Each TPM may be conï¬gured 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, ï¬xed 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:
â Each channel may be input capture, output compare, or buffered edge-aligned PWM
â Rising-edge, falling-edge, or any-edge input capture trigger
â Set, clear, or toggle output compare action
â Selectable polarity on PWM outputs
10.1.3 Block Diagram
Figure 10-2 shows the structure of a TPM. Some MCUs include more than one TPM, with various
numbers of channels.
