STR720 - DRAM CONTROLLER (DRAMC)

106/401

Bank 4 Configuration Register (MB4Config)

Address Offset: 0Ch

Reset value: 0000h

The Bank 4 Configuration Register (MB4Config) is a 16-bit read/write control register used to

configure specific parameters of external region 4 (Bank 4).

The MB4Config control bits are the same as MB1Config register.

Bank 1 SDRAM Configuration Register Low (SDRAM1ConfigLo)

Address Offset: 10h

Reset value: 0000h

The Bank 1 SDRAM Configuration Register Low (SDRAM1ConfigLo) is a 16-bit write only

control register used to configure the SDRAM device of external region 1 (Bank 1).

The SDRAM1ConfigLo control bits are described below.

Bit 15:14 reserved (should be written as zero ).

Bit 13:0

MIAB[13:0]: Memory Interface Address Bus.

This field defines the data to be written in the SDRAM internal configuration

the SDRAM address bus with the value written in SDRAM1ConfigLo register for

one clock period.
