Table 16-8
are set to Phase and Frequency Correct PWM Mode.
Table 16-8.
Table 16-9
are set to single-slope PWM6 Mode. In the PWM6 Mode the same Waveform Output (OCW1A)
is used for generating all waveforms and the Output Compare values OC1A and OC1A are con-
nected on the all OC1x and OC1x pins as described below.
Table 16-9.
Table 16-10
are set to dual-slope PWM6 Mode.I
Table 16-10. Compare Output Mode, Dual-Slope PWM6 Mode
• Bits 5,4 - COM1B1, COM1B0: Comparator B Output Mode, Bits 1 and 0
These bits control the Behavior of the Waveform Output (OCW1B) and the connection of the
Output Compare pin (OC1B). If one or both of the COM1B1:0 bits are set, the OC1B output
overrides the normal port functionality of the I/O pin it is connected to. The complementary
OC1B output is connected only in PWM modes when the COM1B1:0 bits are set to “01”.
