Description
[31:25]
Reserved
Reserved. Any values read should be ignored. When writing to this field always write with
reset value.
[24]
DTCKSEL
Dead-time Clock Select (Write Protected)
0 = Dead-time clock source from PWM_CLK.
1 = Dead-time clock source from prescaler output.
Note:
This register is write protected. Refer to SYS_REGLCTL register.
[23:17]
Reserved
Reserved. Any values read should be ignored. When writing to this field always write with
reset value.
[16]
DTEN
Enable Dead-time Insertion for PWM Pair (PWM_CH0, PWM_CH1) (PWM_CH2,
PWM_CH3) (PWM_CH4, PWM_CH5) (Write Protected)
Dead-time insertion is only active when this pair of complementary PWM is enabled. If dead-
time insertion is inactive, the outputs of pin pair are complementary without any delay.
0 = Dead-time insertion Disabled on the pin pair.
1 = Dead-time insertion Enabled on the pin pair.
Note:
This register is write protected. Refer to SYS_REGLCTL register.
[15:12]
Reserved
Reserved. Any values read should be ignored. When writing to this field always write with
reset value.
[11:0]
DTCNT
Dead-time Counter (Write Protected)
The dead-time can be calculated from the following formula:
Dead-time = (DTCNT[11:0]+1) * PWM_CLK period.
Note:
This register is write protected. Refer to SYS_REGLCTL register.
