Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

INTSTAT Fields

Bit Name Description Access Reset
18 DERRBUSFLG 
This bit is used to indicate that the last transaction was flagged with double-bit error.
1'b0: no effect.
1'b1: indicates double-bit error has occured. This will drive the bus to respond the read with bus error. Write of one will clear this register double-but bus error. 
Bus error occurs as part of the transaction but this indicates the SW the cause of the error. This should only occur once per transaction
 RW 0x0
17 ADDRPARFLG 
External address parity flag for DDR4 memory.
This bit is used to flag external address parity flag which is driven with derr_req port.
1'b0: No Effect. 
1'b1: Read of one indicates double-bit interrupt has occurred.   Write of one will clear this register last address parity flag.
RW 0x0
16 ADDRMTCFLG 
Address mismatch error flag.
This bit is used to indicate the last transaction was flagged with address mismatch error.
1'b0: No effect.
1'b1: indicates address mismatch error has occured. This will drive the bus to respond the read with bus error. Write of one will clears this register address mismatch error.
Bus error occurs as part of the transaction but this indicates the SW the cause of the error. This should occur once per transaction.
 RW 0x0
2 HMI_PENA 
HMI interrupt pending
This bit is used to clear the pending hmi interrupt bit.
1'b0: No effect
1'b1: indicates hmi interrupt is pending. Write of one will clear the pending interrupt. This will de-assert the hmi_intr signal.
 RW 0x0
1 DERRPENA 
Double bit error pending
This bit is used to clear the pending double-bit error.
1'b0: No effect.
1'b1: indicates DBE is pending. Write of one will clear the pending DBE. This will de-assert the derr_req signal.
 RW 0x0
0 SERRPENA 
Single-bit error pending
This bit is used to clear the pending single-bit error.
1'b0: No effect.
1'b1: indicates SBE is pending. Write of one will clear the pending. This will de-assert the serr_req signal.
 RW 0x0
