cycle that is executed for each space selected by the chip select function. By inserting an idle state, the data output
float delay time of the memory can be secured during read access (an idle state cannot be inserted during write
access).
To facilitate interfacing with low-speed memories, one idle state (TI) can be inserted after the T3 state in the bus
Whether the idle state is to be inserted can be programmed by using the BCC register.
An idle state is inserted for all the areas immediately after system reset.
(1) Bus cycle control register (BCC)
Idle State Insertion Function
The BCC register can be read or written in 16-bit units.
Reset sets this register to AAAAH.
Cautions 1. The internal ROM, internal RAM, and on-chip peripheral I/O areas are not subject to idle
Caution Be sure to set bits 15, 13, 11, and 9 to “1”, and set bits 14, 12, 10, 8, 6, 4, 2, and 0 to “0”.
After reset:

access an external memory area until the initial settings of the BCC register are complete.
