Bit 7 — Not implemented
Always reads zero
CON12 — Concatenate Channels One and Two
Channel 1 is high order byte, and channel 2 is the low-order byte. The output appears on port H, bit 1.
Clock source is determined by PCLK2.
0 = Channels 1 and 2 are separate 8-bit PWMs
1 = Channels 1 and 2 are concatenated to create one 16-bit PWM channel.
Bits [5:3] — Not implemented
Always read zero
PCKA[3:1] — Prescaler for Clock A
Determines the rate for clock A
PWPOL can be written anytime. If values in PWPOL are changed during a PWM output, a stretched or
truncated signal may be generated.
Bits [7:6] — Not implemented
Always read zero
PCLK2 — Pulse-Width Channel 2 Clock Select
0 = Clock A is source
1 = Clock S is source
PCLK1 — Pulse-Width Channel 1 Clock Select
0 = Clock A is source
1 = Clock S is source
Bits [3:2] — Not implemented
Always read zero
PWCLK — Pulse-Width Modulation Clock Select
