3.11 Access Mode
This section explains the access mode.
For the read/write access to the external bus interface address area, the following functions area
provided to improve the access efficiency:
1. At read access: Preceding access
2. At write access: Continuous access
The above functions are available only when the frequency division ratio of Division clock register
(DCLKR) is two or more. At the frequency division ratio of 1, the normal access is implemented. Moreover,
the above functions are available at the initial state. So, the functions can be stopped with common
setting register (AMODE: WAEN).
