DTBOTH – Dead-time Concurrent Write to Both Sides
DTBOTHBUF – Dead-time Concurrent Write to Both Sides Buffer
DTLS – Dead-time Low Side Register
• 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 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 next UPDATE condition. If this bit is zero, no action will be taken.
The connected timer/counter unit’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 next UPDATE condition. If this bit is zero, no action will be taken.
The connected timer/counter unit's lock update (LUPD) flag also affects the update for dead-
time buffers.
• Bit 7:0 - DTBOTH: Dead-time Both Sides
Writing to this register will update the DTHS and DTLS registers at the same time (i.e., at the
same I/O write access).
• Bit 7:0 – DTBOTHBUF: Dead-time Both Sides Buffer
Writing to this memory location will update the DTHSBUF and DTLSBUF registers at the same
time (i.e., at the same I/O write access).
