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.
Register Address Bit Name Description
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.
Register Address Bit Name Description
Ln L Clears the Ln bit in the destination registers.
