STRLDSR
Operation:
Assembler Syntax:STRLDSR #<data>
Attributes:
Description: Pushes the contents of the Status Register onto the stack and then reloads the
Status Register with the immediate data value. This instruction is intended for use as the first
instruction of an interrupt service routine shared across multiple interrupt request levels. It allows
the level of the just-taken interrupt request to be stored in memory (using the SR[IML] field), and
then masks interrupts by loading the SR[IML] field with 0x7 (if desired). If execution is attempted
with bit 13 of the immediate data cleared (attempting to place the processor in user mode), a
privilege violation exception is generated. The opcode for STRLDSR is 0x40E7 46FC.
