Reset Value:
This register can only be written if the WPSWS4 and WPHWS4 bits are cleared in
1028.
This register acts as a double buffer for the DTH and DTL values. This prevents an unexpected waveform when modifying
the dead-time values.
Only the first 16 bits (dead-time counter size) of DTHUPD and DTLUPD fields are significant.
• DTLUPD: Dead-Time Value Update for PWMLx Output
• DTHUPD: Dead-Time Value Update for PWMHx Output

Defines the dead-time value for PWMLx output. This value must be defined between 0 and CDTY (CDTYx). This value is
applied only at the beginning of the next channel x PWM period.
Defines the dead-time value for PWMHx output. This value must be defined between 0 and CPRD-CDTY (CPRx and CDTYx).
This value is applied only at the beginning of the next channel x PWM period.
