Description
Loads JKHL with the data whose address is treated either as a logical address that will be passed through
the MMU for translation into a physical address or as a physical address that does not need MMU translation.
If ps is 0xFFFFxxxx, i.e., the upper 16 bits are all ones, it represents a logical address. This is called a
"long logical" address. Otherwise, it is a physical address with the low 20 bits or 24 bits being significant
(depending on the memory available).
The address is computed as the sum of ps and the 8-bit signed displacement d.
