Pulse Width Modulator (PWM)
MC9S12DP256 — Revision 1.1
Pulse Width Modulator (PWM)
CAUTION:
Change these bits only when both corresponding channels are disabled.
CON67 — Concatenate channels 6 and 7
1 = Channels 6 and 7 are concatenated to create one 16-bit PWM
channel. Channel 6 becomes the high order 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.
0 = Channels 6 and 7 are separate 8-bit PWMs.
CON45 — Concatenate channels 4 and 5
1 = Channels 4 and 5 are concatenated to create one 16-bit PWM
channel. Channel 4 becomes the high order 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.
0 = Channels 4 and 5 are separate 8-bit PWMs.
CON23 — Concatenate channels 2 and 3
1 = Channels 2 and 3 are concatenated to create one 16-bit PWM
channel. Channel 2 becomes the high order 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.
0 = Channels 2 and 3 are separate 8-bit PWMs.
CON01 — Concatenate channels 0 and 1
1 = Channels 0 and 1 are concatenated to create one 16-bit PWM
channel. Channel 0 becomes the high order byte and channel
1 becomes the low order byte. Channel 1 output pin is used as
