Operation
TFRA
Before Execution
Rn,Rn
R1
R0
(no parallel move)
TFRA uses the internal AGU data paths, and thus data does not pass through the data limiter.
TFRA
Prior to execution, the R0 register contains the value $009BD6, and R1 contains $1A8C63. After the
TFRA R1,R0 instruction is executed, R0 gets a copy of the value in R1, $1A8C63.
The condition codes are not affected by this instruction.
