> #### Description

> Loads the memory location whose address is computed as the sum of pd and the 8-bit signed displacement d with JKHL.

> The 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 pd 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).
