TFR
Operation:
S.L D.L (parallel data bus move)
Description:
Transfer data from the low portion of the specified source Data ALU register to the low portion of the spec-
ified destination Data ALU register. TFR uses the internal Data ALU paths but does not affect the condition
code bits. When the S and D registers are the same, this instruction is equivalent to an integer rounding
operation.
Input Operand(s) Precision: 32-bit integer.
Output Operand Precision: 32-bit integer.
CCR Condition Codes: Not affected.
ER Status Bits: Not affected.
IER Flags: Not affected.
Instruction Format: TFR
