0–11
Reserved, should be cleared.
12–15
TAG value
ADC_TAG
The ADC_TAG[3:0] represents the TAG for the ADC conversion which is used by the Reaction
[3:0]
Module to select the reaction channel to execute the modulation.
16–31
ADC conversion result value
ADC_RESULT
The ADC_RESULT[15:0] represents the value resulting from an ADC conversion. This value is
[15:0]
used for the Reaction Channel Modulation process or for capturing by the Threshold Bank.

REACM Global Error Flag Register (REACM_GEFR)
The REACM Global Error Flag Register (REACM_GEFR) helps the software in the resolution of error
conditions signaled by the reaction channels. This allows a faster service in error handling. This register
mirrors the Error Flag in the REACM Channel n Status Register (REACM_CHSRn).
Address: REACM_BASE (0xC3FC_7000) + 0x0020

Error Flag
EFn
The EFn error flag bit indicates an error condition occurred in channel n. This bit is provided for a
fast channel error resolution in the Reaction module. The condition could be any error indicated by
MAXL, OCDF, SCDF, SQER, RAER, or TAER error flags as described in
Channel n Status Register
corresponding channel flags are all cleared.
