Matrox Solios eCL/XCL acquisition section 69

You can specify the on/off state of a required output signal and have the PSG

generate and route it to an auxiliary output signal (or auxiliary I/O signals in

output mode) configured as a user signal; your application can set the on/off state

of the signal based on some analysis.

To route the state of a user-bit to an auxiliary output signal, use the MIL-Lite

function MdigControl() with M_IO_SOURCE and M_USER_BITn; to set the

state of a user-bit, use MdigControl() with M_USER_BIT_STATE. To poll the

state of an auxiliary input signal, use MdigInquire() with M_IO_STATUS*,

whereas to have the signal cause an interrupt, use MdigControl() with

M_IO_INTERRUPT_STATE and then use MdigHookFunction() with

M_IO_CHANGE to hook a function to this event (that is, to set up an event

handler).
