Status and Conditions that Affect Instruction

Status and Conditions Changed by Instruction

Example

move.f ($54),d10

MOVE.F (SP+s15),Db

Reads a fractional word from memory. The effective memory address is obtained from the active stack

pointer (SP) with a signed 15-bit offset.

MOVE.F Db,(ea)

Writes an unsaturated fractional word to memory without being affected by the scaling mode. This is the

only instruction available for moving the HP of a data register to memory without saturation. The effective

memory address is obtained from an address register with an optional offset or post-increment.

MCTL[31:0] AM3–AM0 Address modification bits when updating R0–R7. Otherwise, the

instruction is not affected by MCTL.

SR[18] EXP Determines which stack pointer is used when the stack pointer is an

operand. Otherwise, the instruction is not affected by SR.

Ln L Clears the Ln bit in the destination registers.
