Access:
This register can only be written if the bits WPSWS4 and WPHWS4 are cleared in
page
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 12 bits (dead-time counter size) of fields DTHUPD and DTLUPD are significant.
• DTHUPD: Dead-Time Value Update for PWMHx Output
Defines the dead-time value for PWMHx output. This value must be defined between 0 and CPRD-CDTY (PWM_CPRx
and PWM_CDTYx). This value is applied only at the beginning of the next channel x PWM period.
• DTLUPD: Dead-Time Value Update for PWMLx Output
Defines the dead-time value for PWMLx output. This value must be defined between 0 and CDTY (PWM_CDTYx). This
value is applied only at the beginning of the next channel x PWM period.
