Timer/Pulse-Width Modulator (S08TPMV2)
11.1 Introduction
Figure 11-1 shows the MC9S08QD4 series block diagram with the TPM module and pins highlighted.
11.1.1 TPM2 Configuration Information
The TPM2 module consist of a single channel, TPM2CH0, that is multiplexed with input pin PTA4 and
output pin PTA5. When TPM2 is configured for input capture, the TPM2CH0 will connect to the PTA5
(TPM2CH0I). When TPM2 is configured for output compare, the TPM2CH0 will connect to the PTA4
(TPM2CH0O). When TPM2 is disabled, PTA4 and PTA5 function as standard port pins.
11.1.2 TCLK1 and TCLK2 Configuration Information
The TCLK1 and TCLK2 are the external clock source inputs for TPM1 and TPM2 respectively.
