Descriptions
Reserved
This bit is fixed at 1 in on-chip ROM enabled mode, and
0 in on-chip ROM disabled mode. This bit cannot be
changed.
External Bus Mode Enable
Selects external bus mode. In external extended mode,
this bit is fixed 1 and cannot be changed. In single-chip
mode, the initial value of this bit is 0, and can be read
from or written to.
When writing 0 to this bit after reading EXPE = 1, an
external bus cycle should not be executed.
The external bus cycle may be carried out in parallel
with the internal bus cycle depending on the setting of
the write data buffer function.
0: External bus disabled
1: External bus enabled
RAM Enable
Enables or disables the on-chip RAM. This bit is
initialized when the reset state is released. Do not write
0 during access to the on-chip RAM.
0: On-chip RAM disabled
1: On-chip RAM enabled
Reserved
These bits are always read as 0. The write value should
always be 0.
DTC Mode Select
Selects DTC operating mode.
0: DTC is in full-address mode
1: DTC is in short address mode
Reserved
This bit is always read as 1. The write value should
always be 1.
