(5) Chip selector recovery time
If access to external areas occurs consecutively, a dummy cycle can be inserted for recovery time.
The dummy cycle insertion setting can be made in the chip selector and wait controller registers,
BmnCS<BnCSCV>. As for the number of dummy cycles, none, one, two three, four, six and eight system
clocks (internal) can be specified for each block. Fig. 8.10 shows the timing of recovery time insertion.
