Points to Note and Restrictions

6.1

Notation

(1) The notation for built-in I/O registers is as follows register symbol <Bit symbol>

Example: TRUN01<T0RUN> denotes bit T0RUN of register TRUN01.

(2) Read-modify-write instructions (RMW)

An instruction in which the CPU reads data from memory and writes the data to the

same memory location in one instruction.

Example 1:

SET

3, (TRUN01); Set bit3 of TRUN01.

Example 2:

INC

1, (400H); Increment the data at 400H.
