CON23 — Concatenate PWM Channels 2 and 3
CON01 — Concatenate PWM Channels 0 and 1
PCKA2 – PCKA0 — Prescaler for Clock A
PCKB2 – PCKB0 — Prescaler for Clock B
When concatenated, channel 2 becomes the high-order byte and
channel 3 becomes the low-order byte. Channel 2 output pin is used
as the output for this 16-bit PWM (bit 2 of port P). Channel 3 clock-
select control bits determines the clock source. Channel 3 output pin
becomes a general purpose I/O.
When concatenated, channel 0 becomes the high-order byte and
channel 1 becomes the low-order byte. Channel 0 output pin is used
as the output for this 16-bit PWM (bit 0 of port P). Channel 1 clock-
select control bits determine the clock source. Channel 1 output pin
becomes a general purpose I/O.
Clock A is one of two clock sources which may be used for channels
0 and 1. These three bits determine the rate of clock A, as shown in
Table
Clock B is one of two clock sources which may be used for channels
2 and 3. These three bits determine the rate of clock B, as shown in
Table
