SRAMCR specifies the bus interface of each area in the external address space as a basic bus
interface or a byte control SRAM interface.
In areas specified as 8-bit access space by ABWCR, the SRAMCR setting is ignored and the byte
control SRAM interface cannot be specified.

Description
Byte Control SRAM Interface Select
Selects the bus interface for the corresponding area.
When setting a bit to 1, the bus interface select bits in
BROMCR and MPXCR must be cleared to 0.
0: Area n is basic bus interface
1: Area n is byte control SRAM interface
(n = 7 to 0)
Reserved
These are read-only bits and cannot be modified.
