Points of Note and Restrictions

(1) Notation

1. How a built-in I/O register is denoted: Register symbol<Bit symbol>

e.g.)

TRUN<T0RUN>

… Bit T0RUN of register TRUN

2. Read-modify-write instruction

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, (TRUN)

… Set bit3 of TRUN

Example 2:

INC

1, (100H)

… Increment the data at 100H

3. fc, fFPH, fSYS, one state

The clock frequency input from pins X1 and X2 is called fc, the clock selected by

SYSCR<SYSCK> is called fFPH, and the clock frequency given by fFPH divided by 2 is

called fSYS. One cycle of fSYS is called one state.
