STATUS - Status Register
DTBOTH - Dead-time Concurrent Write to Both Sides
Table 15-1.
• Bit 7:3 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 2 - FDF: Fault Detect Flag
This flag is set when a fault detect condition is detected, i.e. when an event is detected on one of
the event channels enabled by the FDEVMASK. This flag is cleared by writing a one to its bit
location.
• Bit 1 - DTHSBUFV: Dead-Time High Side Buffer Valid
If this bit is set the corresponding DT buffer is written and contains valid data that will be copied
into the DTLS Register on the UPDATE condition. If this bit is zero no action will be taken. The
connected Timer/Counter’s lock update (LUPD) flag also affects the update for dead time
buffers.
• Bit 0 - DTLSBUFV: Dead-Time Low Side Buffer Valid
If this bit is set the corresponding DT buffer is written and contains valid data that will be copied
into the DTHS Register on the UPDATE condition. If this bit is zero no action will be taken. Note
that the connected Timer/Counter unit's lock update (LUPD) flag also affects the update for dead
time buffers.
