11.4.4
CSnWCR (n = 0 to 6) are 32-bit readable/writable registers that specify the number of wait cycles
to be inserted for areas 0 to 6, the number of wait cycles to be inserted preceding the first data in
burst memory access, the address setup time, which is the time from the point at which the output
of address for access is started until assertion of the read/write strobe signal, and the number of
cycles to be inserted as the data hold time from negation of the write strobe signal.
CSnWCR is initialized to H'7777 770F by a power-on reset, but it is not initialized by a manual
reset.

Description
Reserved
This bit is always read as 0. The write value should
always be 0.
Address Setup Cycle
These bits specify the number of cycles to be inserted
as the address setup time with respect to CSn
assertion. (Only valid when the SRAM interface, byte
control SRAM interface, or burst ROM interface is
selected.)
000: No cycle inserted
001: 1 cycle inserted
010: 2 cycles inserted
011: 3 cycles inserted
100: 4 cycles inserted
101: 5 cycles inserted
110: 6 cycles inserted
111: 7 cycles inserted
