Timer Pulse-Width Modulator (S08TPMV3)
16.1
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, 0–1). The TPM shares its I/O pins with
general-purpose I/O port pins (refer to the
All MC9S08SG32 Series MCUs have two TPM modules.

16.1.1
The external clock for the MTIM module, TCLK, is selected by setting CLKS = 1:1 or 1:0 in MTIMCLK,
which selects the TCLK pin input. The TCLK input can be enabled as external clock inputs to both the
MTIM and TPM modules simultaneously.

The TPM modules pins, TPM1CHx and TPM2CHx can be repositioned under software control using
TxCHnPS bits in SOPT2 as shown in
