Bit
Description
0
System service request response disabled
1
System service request response enable
System software can set this bit to indicate that the MediaLB Device is present and needs service.

generated when MediaLB unlock is detected.
Write "1" to clear this bit. Writing "0" has no effect. Once set, this bit holds until it is cleared by software.
Note:
−
During the locked state, this bit is set to "1" when the MLBn_DCCR:MRS bit is set to "1".
