• Manufacturer Part Number: msm7630
• Description: Universal Speech Processor
• Manufacturer: Oki Semiconductor

¡ Semiconductor
• bit[12:10] ORW: ROM Read Wait (read/write)
• bit[9:8] OS: ROM Device Size (read/write)
• bit[7] DS: Other Data Setup (read/write)
• bit[6] PC: Other Parity Check (read/ write)
These bits set the wait count when ROM space is accessed by a read.
These bits will be "111" after reset.
These bits set the device size of ROM space.
When this field is "00", attempting to access ROM space will cause an instruction access exception
or data access exception.
This bit sets whether or not the data setup time to the write strobe signal WR is guaranteed during
writes to general device space.
This bit will be "1" after reset.
This bit sets parity checking for general device space. It will be "0" after reset.
This bit will be "0" for the MSM7630.
