2.3 H Register and L Register

The H register and L register are 4-bit general registers. They

are also used as a register pair (HL) for the data memory (RAM)

addressing pointer. The RAM consists of pages, each page

being 16 words long (1 word = 4 bits). The H register speciﬁes

a page and the L register speciﬁes an address in the page.

The L register has the auto-post-increment/decrement

capability, implementing the execution of composite instruc-

tions. For example, [ST A, @HL+] instruction automatically in-

crements the contents of the L register after data transfer.

During the execution of [SET @L], [CLR @L], or [TEST @L]

instructions, the L register is also used to specify the bits cor-

responding to I/O port pins R73 through R40 (the indirect ad-

dressing of port bits by the L register).

Example: To Write immediate values “5” and FH” to data

memory addresses 10H and 11H.
