bit[12:11] SZ: Device Size (read/write)
These bits set the device size of DRAM space.
SZ = 00
SZ = 01
SZ = 10
SZ = 11
No DRAM (space is invalid)
8-bit wide device
16-bit wide device
32-bit wide device
These bits will be "00" after reset. When this field is "00", attempting to access DRAM space will
cause an instruction access exception or data access exception.
bit[10] RFM: Refresh Mode (read/write)
This bit sets the refresh operation mode.
RFM = 0
RFM = 1
CAS-before-RAS refresh
CAS-before-RAS self-refresh
This bit will be "0" after reset.
bit[9:0] RFC: Refresh Counter (read/write)
These bits set the initial value of the refresh counter. It should be set as an integer value obtained
by:
[(refresh period)
÷
(clock period)
÷
16]–1
These bits will be "0000000000" after reset.
