CDBGMOD[1:0] — Interrupts for control endpoint 0
DDBGMODIN[1:0] — Interrupts for DATA IN endpoints 1 to 7
DDBGMODOUT[1:0] — Interrupts for DATA OUT endpoints 1 to 7
The Debug mode settings for CDBGMOD, DDBGMODIN and DDBGMODOUT allow you
to individually configure when the ISP1582 sends an interrupt to the external
microprocessor.
Bit INTPOL controls the signal polarity of the INT output: active HIGH or LOW, rising or
falling edge. For level-triggering, bit INTLVL must be made logic 0. By setting INTLVL to
logic 1, an interrupt will generate a pulse of 60 ns (edge-triggering).

Description
Control Endpoint 0 Debug Mode: For values, see
Data Debug Mode IN: For values, see
Interrupt Level: Selects signaling mode on output INT (0 = level;
1 = pulsed). In pulsed mode, an interrupt produces a 60 ns pulse.
Interrupt Polarity: Selects signal polarity on output INT (0 =
active LOW; 1 = active HIGH).
