39.7.43 PWM Channel Dead Time Update Register
Name:
PWM_DTUPDx [x=0..3]
Address:
0x4002021C [0], 0x4002023C [1], 0x4002025C [2], 0x4002027C [3]
Access:
Write-only
This register can only be written if bits WPSWS4 and WPHWS4 are cleared in the
.
This register acts as a double buffer for the DTH and DTL values. This prevents an unexpected waveform when modifying
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.
