CON34 —Concatenate Channels 3 and 4
Channel 3 is high-order byte, and channel 4 (port H, bit 3) is output. Clock source is determined by
PCLK4.
0 = Channels 3 and 4 are separate 8-bit PWMs.
1 = Channels 3 and 4 are concatenated to create one 16-bit PWM channel.
CON12 —Concatenate Channels One and Two
Channel 1 is high order byte, and channel 2 (port H, bit 1) is output. 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.
PCKA[2:1] —Prescaler for Clock A (See also PWSCAL register)
