16.7 Register Description
16.7.1 CTRL – Control register
• Bit 7:6 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 5 – PGM: Pattern Generation Mode
Setting this bit enables the pattern generation mode. This will override the DTI, and the pattern
generation reuses the dead-time registers for storing the pattern.
• Bit 4 – CWCM: Common Waveform Channel Mode
If this bit is set, the CC channel A waveform output will be used as input for all the dead-time
generators. CC channel B, C, and D waveforms will be ignored.
• Bit 3:0 – DTICCxEN: Dead-Time Insertion CCx Enable
Setting these bits enables the dead-time generator for the corresponding CC channel. This will
override the timer/counter waveform outputs.
16.7.2 FDEMASK – Fault Detect Event Mask register
• Bit 7:0 – FDEVMASK[7:0]: Fault Detect Event Mask
These bits enable the corresponding event channel as a fault condition input source. Events
from all event channels will be ORed together, allowing multiple sources to be used for fault
detection at the same time. When a fault is detected, the fault detect flag (FDF) is set and the
fault detect action (FDACT) will be performed.
