The Interrupt Configuration register of the ISP1582 controls the behavior of the INT output
pin. The polarity and signaling mode of pin INT can be programmed by setting bits
INTPOL and INTLVL of the Interrupt Configuration register (R/W: 10h); see
GLINTENA of the Mode register (R/W: 0Ch) is used to enable pin INT. Default settings
after reset are active LOW and level mode. When pulse mode is selected, a pulse of 60 ns
is generated when the OR-ed combination of all interrupt bits changes from logic 0 to
logic 1.
Figure 3
Each of the indicated USB and DMA events is logged in a status bit of the Interrupt
register and the DMA Interrupt Reason register, respectively. Corresponding bits in the
Interrupt Enable register and the DMA Interrupt Enable register determine whether an
event will generate an interrupt.
Interrupts can be masked globally by means of bit GLINTENA of the Mode register; see
