3.4 SCR: Space Configuration Register
This register sets ROM space, SRAM space, and general device space.
• bit[25] AC: SRAM Parity Check (read/write)
• bit[24] AD: SRAM Dummy Cycle (read/write)
• bit[23:21] ARW: SRAM Read Wait (read/write)
bit
This bit sets parity checking of SRAM space. It will be "0" after reset.
This bit sets whether or not SRAM space may be accessed continuously after ROM space or DRAM
space has been read.
This bit will be "1" after reset.
These bits set the wait count when SRAM space is accessed by a read.
These bits will be "111" after reset.

Ignore parity checks.
Generate a bus error if a parity error is detected.
Continuous access allowed.
Open an interval of at least one clock.
