4.4.1 Bus cycle type configuration
(1)
Bus cycle configuration registers 0, 1 (BCT0, BCT1)
These registers can be read/written in 16-bit units
Cautions: 1. Write to the BCT0 and BCT1 registers after reset, and then do not change the set
value. Also, do not access an external memory area other than that for this
initialization routine until initial setting of the BCT0 and BCT1 registers is
finished. However, it is possible to access external memory areas whose
initialization has been finished.
2. The bits marked as 0 and 1 are reserved.
The values of these bits must not be
changed. Otherwise the operation of the external bus interface cannot be
ensured.
