Section 8 Bus State Controller (BSC)
8.4.3
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.
CSnWCR is initialized to H'00000500 by a power-on reset and retains the value by a manual reset
and in software standby mode.
