In the
(1) Bus cycle type configuration register 0 (BCT0)
This register can be read or written in 16-bit units.
Reset sets this register to CCCCH.
Cautions 1. Do not access an external memory area until the initial setting of the BCT0 register is
Caution Be sure to set bits 0, 1, 4, 5, 8, 9, 12, and 13 to “0”, and set bits 2, 6, 10, 11, 14, and 15 to
