Register 0xFECA and Register 0xFECB record the first flag ID for Channel A and Channel B, respectively. The first flag ID represents the
first flag that triggers a response and requires a soft start after the fault is resolved. The Channel A first flag ID register (Register 0xFECA)
records the first flag ID of the fault that shut down Channel A; the Channel B first flag ID register (Register 0xFECB) records the first flag
ID of the fault that shut down Channel B. For more information, see the First Flag ID Recording section.

Description
Reserved.
Temperature of Zone 2 is above the OTW2 threshold.
Temperature of Zone 1 is above the OTW1 threshold.
CS2_B reverse current falls below the CS2_B reverse current
threshold.
CS2_A reverse current falls below the CS2_A reverse current
threshold.
Description
These bits return the flag fault ID of the flag that caused the previous shutdown of Channel A or
Channel B. This previous shutdown occurred before the shutdown caused by the fault identified
in Bits[3:0].
