Concatenate Channels 6 and 7
0 Channels 6 and 7 are separate 8-bit PWMs.
1 Channels 6 and 7 are concatenated to create one 16-bit PWM channel. Channel 6 becomes the high order
Concatenate Channels 4 and 5
0 Channels 4 and 5 are separate 8-bit PWMs.
1 Channels 4 and 5 are concatenated to create one 16-bit PWM channel. Channel 4 becomes the high order
Concatenate Channels 2 and 3
0 Channels 2 and 3 are separate 8-bit PWMs.
1 Channels 2 and 3 are concatenated to create one 16-bit PWM channel. Channel 2 becomes the high order
Concatenate Channels 0 and 1
0 Channels 0 and 1 are separate 8-bit PWMs.
1 Channels 0 and 1 are concatenated to create one 16-bit PWM channel. Channel 0 becomes the high order
PWM Stops in Wait Mode — Enabling this bit allows for lower power consumption in wait mode by disabling
the input clock to the prescaler.
0 Allow the clock to the prescaler to continue while in wait mode.
1 Stop the input clock to the prescaler whenever the MCU is in wait mode.
PWM Counters Stop in Freeze Mode — In freeze mode, there is an option to disable the input clock to the
prescaler by setting the PFRZ bit in the PWMCTL register. If this bit is set, whenever the MCU is in freeze mode,
the input clock to the prescaler is disabled. This feature is useful during emulation as it allows the PWM function
to be suspended. In this way, the counters of the PWM can be stopped while in freeze mode so that once normal
program flow is continued, the counters are re-enabled to simulate real-time operations. Since the registers can
still be accessed in this mode, to re-enable the prescaler clock, either disable the PFRZ bit or exit freeze mode.
0 Allow PWM to continue while in freeze mode.
1 Disable PWM input clock to the prescaler whenever the part is in freeze mode. This is useful for emulation.
Reserved Register (PWMTST)
byte and channel 7 becomes the low order byte. Channel 7 output pin is used as the output for this 16-bit
PWM (bit 7 of port PWMP). Channel 7 clock select control-bit determines the clock source, channel 7 polarity
bit determines the polarity, channel 7 enable bit enables the output and channel 7 center aligned enable bit
determines the output mode.
byte and channel 5 becomes the low order byte. Channel 5 output pin is used as the output for this 16-bit
PWM (bit 5 of port PWMP). Channel 5 clock select control-bit determines the clock source, channel 5 polarity
bit determines the polarity, channel 5 enable bit enables the output and channel 5 center aligned enable bit
determines the output mode.
byte and channel 3 becomes the low order byte. Channel 3 output pin is used as the output for this 16-bit
PWM (bit 3 of port PWMP). Channel 3 clock select control-bit determines the clock source, channel 3 polarity
bit determines the polarity, channel 3 enable bit enables the output and channel 3 center aligned enable bit
determines the output mode.
byte and channel 1 becomes the low order byte. Channel 1 output pin is used as the output for this 16-bit
PWM (bit 1 of port PWMP). Channel 1 clock select control-bit determines the clock source, channel 1 polarity
bit determines the polarity, channel 1 enable bit enables the output and channel 1 center aligned enable bit
determines the output mode.
