Escaped Mode Addressing
This instruction performs an arithmetic shift to the right by one bit position on the destina-
tion operand. Bit 0 replaces the Carry (C) flag. The value of Bit 7 (the Sign bit) does not
change, but its value shifts into Bit 6.
Using Escaped Mode Addressing, address modes R or IR can specify a Working Register.
If the destination address is prefixed by
example, if Working Register R12 (
