2.3 Special Registers
These are not privileged registers, but they are special registers used for specific functions.
2.3.1 NOP: Non-Operation (read/write)
When this register is specified as a destination register, execution results will not be stored anywhere.
When specified as a source register, it will read as an undefined value.

3. Data Formats
There are two data format types: one for internal processor core calculations and one for memory
accesses.
3.1 Internal Data Format
The CPU core handles all data as 32 bits (word format). Therefore, when the format of data stored
in memory is byte (8 bits) or half-word (16 bits) it must be used internally as 32-bit data through a
signed load instruction or unsigned load instruction. Similarly when internal core processing results
are stored to memory, a store instruction corresponding to the data format in memory must be
executed. Also, bit addresses specified for bit test instructions and bit manipulation instructions are
shown in the diagram below.
