> #### Description

> Loads the 32-bit register BCDE 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 or 24 bits (depending on the memory that is used) being significant.

> The address is computed as the sum of ps and the 8-bit signed displacement d.
