WO 0x0
If the Retry State Machine (RSM) is in fatal error state (RetryFata‐
lError), writing the value of 1 to this register field causes the RSM
to resume normal operation.
When a RetryFatalError occurs, the RSM halts and waits for
external corrective action. Writing the value of 1 to this register
field forces the RSM to continue.
This bit is self-clearing. It clears whether or not it affects the RSM
state.
