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.

Memory Address
This register is the address and command/status register for the Flash memory interface. The register bits are defined below.
Bit [31]
: GPIO Enable (R/W). This bit, when set to one, enables the use of the Flash Data pins for General Purpose
I/O.
Bit [30:27]
: Reserved (R). This bit field is reserved and returns ‘0001’ on a read.
Bit [26]
: Mem Present (R) – Memory Present. This bit set indicates that the auto-initialization signature was
read correctly from the Flash Memory.
Bit [25]
: Mem Access Start (R/W) – Memory Access Start. This bit is set to initiate an operation to Flash
memory. This bit is self-clearing when the operation is complete.
Bit [24]
: Mem Access Type (R/W) – Memory Access Type. This bit is set to define a read operation from Flash
memory. This bit is cleared to define a write operation to Flash memory.
Bit [23:19]
: Reserved (R). This bit field is reserved and returns zeros on a read.
Bit [18:00]
: Memory Address (R/W). This bit field is programmed with the address for a Flash memory read or
write access.
