Points to Note and Restrictions
(1) Notation
1.
The notation for built-in I/O registers is as follows register symbol <Bit symbol>.
Example:
2.
Read-modify-write instructions (RMW)
An instruction in that the CPU reads data from memory and writes the data to the
same memory location by using one instruction.
Example 1: SET
Example 2: INC
