CP.H – Compare Halfword
Architecture revision:
Architecture revision1 and higher.
Description
Performs a compare between the lowermost halfwords in the two operands specified. The oper-
ation is implemented by doing a subtraction without writeback of the difference. The operation
sets the status flags according to the result of the subtraction, but does not affect the operand
registers.
Operation:
I.
Syntax:
I.
Operands:
