2.1 EID#702 DFL Deny Interrupts Might not Be Valid
Description The LCM interrupt register contains a list of admission rejection (deny) interrupts, which are triggered based on the
deny reason.
Erratum When triggered, the LCM.AdmitDenyLCMFullInt interrupt may trigger additional interrupts
(LCM.AdmitDenyDueSharedMemInt, LCM.AdmitDenyDueDtmInt, and LCM.AdmitDenyDueLatencyInt), making
them false alarms.
Workaround If LCM.AdmitDenyLCMFullInt is set, ignore the following interrupts:
LCM.AdmitDenyDueSharedMemInt
LCM.dmitDenyDueDtmInt
LCM.dmitDenyDueLatencyInt interrupts
