Many usb8x functions can be by other programs/applications through usb8x's assembly language U_CALL interface. Macros are provded in usb8x.inc to simplify the process. The macros require a 32-byte RAM buffer to be defined as USBDriverCall. The U_CALL system must be initialized by the application as follows:
U_CALL_INIT CallBackRoutine
Where callback routine is a subroutine that will be called when data arrives on the USB port.
After the U_CALL system has been initialized with U_CALL_INIT, use the U_CALL macro to call usb8x entry points. Entry points are:
| DriverInit | Initialize the USB driver |
| HostInit | Initialize a USB device |
| HostKill | Uninitialize a USB device |
