BIST Pattern
This register contains the 32-bit fixed pattern that is repeatedly transmitted in data loopback when the BISTpatsel bit (bit 30) of
the BIST Control register is set to 1.
6.2.7
BIST Status Register
Address Offset: 58H
Access Type: Read
Reset Value: 0x8000_0000

BISTgood
Reserved
BISTerrcnt
Bit [31]: BISTgood (R) – This bit indicates that all comparisons have been good since initiating data loopback
BIST. This bit is initialized (to 1) when the BISTenable bit is zero in the BIST Control register.
Bit [30:12]: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [11:00]: BISTerrcnt (R). This bit field indicates the number of comparisons that have been in error since
initiation of data loopback BIST. This counter is a saturating counter (it stops counting at 0FFFH). This counter
is cleared when the BISTenable bit is zero in the BIST Control register.
6.2.8
MemBIST Status Register
Address Offset: 5CH
Access Type: Read
Reset Value: 0x0000_0000

MemBIST Status
Reserved
LRAM1
Buffe
r1
LRAM0
Buffe
r0
Bit [31:08]: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [07:00]: MemBIST Status (R). This bit field indicates the status of MemBIST for each RAM. Each status bit
is set to 1 for a successful test.
6.2.9
Configuration Register Offset
Address Offset: 78H
Access Type: Read/Write
Reset Value: 0x0000_0000
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
Reserved
Dword Offset
00
This register provides indirect addressing of a Configuration Register. The Dword address offset for an indirect access is in
bits 11 to 2; bits 31 to 12, 1, and 0 are reserved and should always be 0.
