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 attributes
(Note 1)
(Note 2)
Bit position
2: 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 :
: Bit in which nothing is assigned
Notes 1: Values immediately after reset release
0 “0” after reset release
1 “1” after reset release
IndeterminateIndeterminate after reset release
