Hardware

The game's microprocessor can handle up to 65535 hardware devices connected to addresses 0x0000-0xFFFF. Hardware devices can interact with the CPU, its memory and its registers.

The HWQ (Hardware Query) instruction can be used to get information about the hardware connected at an address.

Example:

MOV A, 0x0005
HWQ A
; The hardware id of the hardware at address 0x0005 is stored in the B register
; If there is no hardware device connected at this address, B = 0

The HWI (Hardware Interupt) instruction sends an interrupt to the hardware device at the specified address

INVENTORY_HW equ 0x0006 ; An inventory module is connected at address 0x006. Define a constant
MOV A, 1 ; The Inventory hardware expects 1 (POLL) or 2 (CLEAR)
HWI INVENTORY_HW
; B = current held item id
