Description

If condition cx is true then program execution is transferred to the memory location specified by the 16-bit constant, mn. A jump can be made to a computed address in extended memory by loading the 12-bit XPC with the 16-bit constant lxpc (the 4 most significant bits of lxpc are discarded). Note that the value of the 12-bit XPC and consequently the address space defined by it is dynamically changed with this instruction.

This instruction recognizes labels when used in the Dynamic C assembler.
