(1) Data wait control register 0 (DWC0)
Wait Function
To realize interfacing with a low-speed memory or I/O, up to seven data wait states can be inserted in the bus cycle
that is executed for each memory block space.
The number of wait states can be programmed by using the DWC0 register . Immediately after system reset, 7
data wait states are inserted for all the blocks.
The DWC0 register can be read or written in 16-bit units.
Reset sets this register to 7777H.
Cautions 1. The internal ROM and internal RAM areas are not subject to programmable wait, and are
Programmable wait function
Caution Be sure to clear bits 15, 11, 7, and 3 to “0”.
2. Write to the DWC0 register after reset, and then do not change the set values. Also, do not

programmable wait, and only wait control from each peripheral function is performed.
