SYSREG Control Registers
The registers listed in the following table control the behavior of the eSRAM. These registers are detailed
in
and are listed here for clarity. Refer to the
page 670 for a detailed
description of each register and bit.

Description
(0x40038000) RW-P
Register
SYSRESET_N
Controls address mapping of the
eSRAMs.
(0x40038004)
RW-P
Register
SYSRESET_N
Configuration of maximum latency for
accessing eSRAM_0 and eSRAM_1
slaves. This register gets updated by
flash bit configuration set during device
programming. This configuration can be
done through the
System Builder
also
using settings on the
Microcontroller
Tab
.
(0x40038080)
RW-P
Register
SYSRESET_N
Controls the pipeline present in the
memory read path of eSRAM memory.
(0x400380F0)
RO
N/A
SYSRESET_N
Represents 1-bit error count of
eSRAM_0.
(0x400380F4)
RO
N/A
SYSRESET_N
Represents 1-bit error count of
eSRAM_1.
(0x4003810C)
RO
N/A
SYSRESET_N
Address from eSRAM_0 on which 1-bit
ECC error has occurred.
(0x40038110)
RO
N/A
SYSRESET_N
Address from eSRAM_1 on which 1-bit
ECC error has occurred.
(0x40038124)
RO-U
N/A
SYSRESET_N
Read and Write security for Mirrored
Master (MM) 0, 1, and 2 to eSRAM_0
and eSRAM_1.
MM4_5_DDR_FIC_SECUR
ITY/MM4_5_FIC64_SECU
RITY
(0x40038128)
RO-U
N/A
SYSRESET_N
Read and Write security for Mirrored
Master (MM) 4, 5, and DDR_FIC to
eSRAM_0 and eSRAM_1. This register
gets updated by flash bit configuration
set during device programming. This
configuration can be done through the
System Builder
using settings on the
Security
tab.
(0x4003812C)
RO-U
N/A
SYSRESET_N
Read and Write security for Mirrored
Master (MM) 3, 6, 7, and 8 to eSRAM_0
and eSRAM_1. This register gets
updated by flash bit configuration set
during device programming. This
configuration can be done through the
System Builder
using settings on the
Security
tab.
