> #### Description

> These instructions are used to access 20-bit addresses. In all cases, the four most significant bits of the 20- bit address (bits 19 through 16) are defined as the four least significant bits of A (bits 3 though 0). The LDP instructions bypass the MMU's address translation unit for direct access to the 20-bit memory address space.

> - `LDP (HL),HL:` Loads the memory location whose 16 least significant bits of its 20-bit address are the data in HL with the data in L, and then loads the following 20-bit address with the data in H.

> - `LDP (IX),HL:` Loads the memory location whose 16 least significant bits of its 20-bit address are the data in IX with the data in L, and then loads the following 20-bit address with the data in H.

> - `LDP (IY),HL:` Loads the memory location whose 16 least significant bits of its 20-bit address are the data in IY with the data in L, and then loads the following 20-bit address with the data in H.

> Note that the LDP instructions wrap around on a 64K page boundary. Since the LDP instruction operates on two-byte values, the second byte will wrap around and be written at the start of the page if you try to read or write across a page boundary. Thus, if you fetch or store at address 0xn,0xFFFF, you will get the bytes located at 0xn, 0xFFFF and 0xn,0x0000 instead of 0xn,0xFFFF and 0x(n+1),0x0000 as you might expect. Therefore, do not use LDP at any physical address ending in 0xFFFF.
