MC68HC11G5
CON12 — Concatenate channels 1 and 2
PCKA2, PCKA1 — Prescaler for clock A
PCKB3, PCKB2, PCKB1 — Prescaler for clock B
1 – Channels 1 and 2 are concatenated to create one 16-bit PWM channel. (Channel
0 – Channels 1 and 2 are separate 8-bit PWM channels.
Clock A is one of two clock sources which may be used for channels 1 & 2. These two
bits determine the rate of clock A.
Clock B is one of two clock sources which may be used for channels 3 & 4. These three
bits determine the rate of clock B.
1 becomes the high order byte and channel 2 becomes the low order byte. The
channel 2 output is used as the output for this 16-bit PWM (bit 1 of Port H)).
