CSn Space Wait Control Register (CSnWCR) (n = 0 to 6)
CSnWCR specifies various wait cycles for memory access. The bit configuration of this register
varies as shown below according to the memory type (TYPE2 to TYPE0) specified by the CSn
space bus control register (CSnBCR). Specify CSnWCR before accessing the target area. Specify
CSnBCR first, then specify CSnWCR.
