Notes and Restrictions
6.1
Notation
(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.
Example 1: SET 3, (TA01RUN); Set bit3 of TA01RUN.
Example 2: INC 1, (100H); Increment the data at 100H.

and one state
The clock frequency input on pins X1 and 2 is referred to as f
OSCH
. The clock selected by
PLLCR0<FCSEL> is referred to as fc.
The clock selected by SYSCR1<GEAR2:0> is referred to as system clock f
SYS
. The clock
frequency given by f
SYS
divided by 2 is referred to as f
IO
.
One cycle of f
SYS
is referred to as one state.
