CON34 — Concatenate Channels 3 and 4 Bit
CON12 — Concatenate Channels 1 and 2 Bit
PCKA[2:1] — Prescaler for Clock A Bits
PCKB[3:1] — Prescaler for Clock B Bits
Channel 3 is the high-order byte, and channel 4 (port H, bit 3) is
output.
Channel 1 is the high-order byte, and channel 2 (port H, bit 1) is
output.
These bits select the frequency for clock A as shown in
These bits select the frequency for clock B as shown in

0 = Channels 3 and 4 are separate 8-bit PWMs.
1 = Channels 3 and 4 are concatenated to create one 16-bit PWM.
0 = Channels 1 and 2 are separate 8-bit PWMs.
1 = Channels 1 and 2 are concatenated to create one 16-bit PWM.
