[Function]
Register direct addressing stores in the program counter (PC) the contents of a general-purpose register pair
(AX/BC/DE/HL) and CS register of the current register bank specified with the instruction word as 20-bit data, and
specifies the program address. Register direct addressing can be applied only to the CALL AX, BC, DE, HL, and BR
AX instructions.
