Cash Drawer Support
An integrated retail specific feature of the processor is the cash drawer
circuitry. The onboard circuitry internal to the board provides the
control for two external cash drawers. A portion of the POS Board
header (J6) is provided on the board to interface to the dual cash
drawer connector. Header J6 only contains the control signals; it does
not provide power. Software controls the cash drawer(s) through I/O
port 00Exh. This means it can be I/O ports E0/E1h, E2/E3h, E4/E5h,
or EA/EBh depending on the configuration of the SMC I/O
controller's GPIO port(s). Default setting is E0/E1h.
