9.4.2
CSn Space Bus Control Register (CSnBCR) (n = 0 to 7)
CSnBCR is a 32-bit readable/writable register that specifies the function of each area, the number
of idle cycles between bus cycles, and the bus width.
Do not access external memory other than area 0 until CSnBCR initial setting is completed.
Idle cycles may be inserted even when they are not specified. For details, see section 9.5.12, Wait
between Access Cycles.
