bit[12:10] ORW: ROM Read Wait (read/write)
These bits set the wait count when ROM space is accessed by a read.
ORW = 000
ORW = 001
ORW = 010
ORW = 011
ORW = 100
ORW = 101
ORW = 110
ORW = 111

These bits will be "111" after reset.
bit[9:8] OS: ROM Device Size (read/write)
These bits set the device size of ROM space.
OS = 00
OS = 01
OS = 10
OS = 11
No ROM (space is invalid)
8-bit wide device
16-bit wide device
32-bit wide device
When this field is "00", attempting to access ROM space will cause an instruction access exception
or data access exception.
bit[7] DS: Other Data Setup (read/write)
This bit sets whether or not the data setup time to the write strobe signal
WR
is guaranteed during
writes to general device space.
DS = 0
DS = 1
Not guaranteed.
Guaranteed.
This bit will be "1" after reset.
bit[6] PC: Other Parity Check (read/ write)
This bit sets parity checking for general device space. It will be "0" after reset.
PC = 0
PC = 1
Ignore parity errors.
Generate a bus error if a parity error is detected.
This bit will be "0" for the MSM7630.
