Points of Note and Restrictions

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

Example: TA01RUN<TA0RUN> denotes bit TA0RUN of register TA01RUN.

(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.

Examples of read-modify-write instructions on the TLCS-900:

Exchange instruction

Arithmetic operations

ADD (mem), R/#

SUB (mem), R/#

INC #3, (mem)

Logic operations

AND (mem), R/#

XOR (mem), R/#

Bit manipulation operations

STCF #3/A, (mem)

SET #3, (mem)

TSET #3, (mem)

Rotate and shift operations

The clock frequency input on pins X1 and 2 is referred to as f

PLLCR0<FCSEL> is referred to as fc.

The clock selected by SYSCR1<SYSCK> is referred to as f

divided by 2 is referred to as system clock f

divided by 2 is referred to as f

One cycle of f

3, (TA01RUN); Set bit3 of TA01RUN.

1, (100H); Increment the data at 100H.
