3.5.6 Computed Long Calls and Jumps
The instruction to set the XPC is privileged to so that a computed long call or jump can be
made. This would be done by the following sequence.
In this case, A has the new XPC, and HL has the new PC. This code should normally be
executed in the root segment so as not to pull the memory out from under the JP (HL)
instruction.
A call to a computed address can be performed by the following code.
