Structure of Register
The figure of each register structure describes its functions, contents
at reset, and attributes as follows:
Values immediately after reset release

Bit attributesThe attributes of control register bits are classified into 3 types : read-only, write-only
and read and write. In the figure, these attributes are represented as follows :
RRead
WWrite
: Bit in which nothing is assigned
Notes 1:
Values immediately after reset release
0“0” after reset release
1“1” after reset release
Indeterminate after reset release
Read enabled
