bit 7-6
DTC<1:0>: Dead-Time Control bits
11 = Dead-Time Compensation mode
10 = Dead-time function is disabled
01 = Negative dead time actively applied for Complementary Output mode
00 = Positive dead time actively applied for all output modes
11 = Dead-Time Compensation mode
10 = Dead-time function is disabled
01 = Negative dead time actively applied for Complementary Output mode
00 = Positive dead time actively applied for all output modes
bit 5
DTCP: Dead-Time Compensation Polarity bit
(3)
When set to ‘1’:
If DTCMPx = 0, PWMxL is shortened and PWMxH is lengthened.
If DTCMPx = 1, PWMxH is shortened and PWMxL is lengthened.
When set to ‘0’:
If DTCMPx = 0, PWMxH is shortened and PWMxL is lengthened.
If DTCMPx = 1, PWMxL is shortened and PWMxH is lengthened.
If DTCMPx = 0, PWMxL is shortened and PWMxH is lengthened.
If DTCMPx = 1, PWMxH is shortened and PWMxL is lengthened.
When set to ‘0’:
If DTCMPx = 0, PWMxH is shortened and PWMxL is lengthened.
If DTCMPx = 1, PWMxL is shortened and PWMxH is lengthened.
bit 4
Unimplemented: Read as ‘0’
bit 3
MTBS: Master Time Base Select bit
1 = PWM generator uses the secondary master time base for synchronization and as the clock source
1 = PWM generator uses the secondary master time base for synchronization and as the clock source
for the PWM generation logic (if secondary time base is available)
0 = PWM generator uses the primary master time base for synchronization and as the clock source
for the PWM generation logic
bit 2
CAM: Center-Aligned Mode Enable bit
(2,4)
1 = Center-Aligned mode is enabled
0 = Edge-Aligned mode is enabled
0 = Edge-Aligned mode is enabled
bit 1
XPRES: External PWM Reset Control bit
(5)
1 = Current-limit source resets the time base for this PWM generator if it is in Independent Time Base
mode
0 = External pins do not affect PWM time base
bit 0
IUE: Immediate Update Enable bit
1 = Updates to the active MDC/PDCx/SDCx registers are immediate
0 = Updates to the active PDCx registers are synchronized to the PWM time base
1 = Updates to the active MDC/PDCx/SDCx registers are immediate
0 = Updates to the active PDCx registers are synchronized to the PWM time base
REGISTER 16-11: PWMCONx: PWM CONTROL REGISTER (CONTINUED)
Note 1: Software must clear the interrupt status here and in the corresponding IFS bit in the interrupt controller.
2: These bits should not be changed after the PWM is enabled (PTEN = 1).
3: DTC<1:0> = 11 for DTCP to be effective; otherwise, DTCP is ignored.
4: The Independent Time Base (ITB = 1) mode must be enabled to use Center-Aligned mode. If ITB = 0, the
3: DTC<1:0> = 11 for DTCP to be effective; otherwise, DTCP is ignored.
4: The Independent Time Base (ITB = 1) mode must be enabled to use Center-Aligned mode. If ITB = 0, the
CAM bit is ignored.
5: To operate in External Period Reset mode, the ITB bit must be ‘1’ and the CLMOD bit in the FCLCONx
register must be ‘0’.
