MC68HC11KA4
MC68HC11KA4TS/D
Scaled clock S is generated by dividing clock A by the value in PWSCAL, then dividing the result by 2.
If PWSCAL = $00, divide clock A by 256, then divide the result by 2.
Always read zero
PWPOL —Pulse-Width Modulation Timer Polarity
PWSCAL — Pulse-Width Modulation Timer Prescaler
PWEN — Pulse-Width Modulation Timer Enable
