13. Interrupts
Figure 8
shows the interrupt logic of the ISP1181B. Each of the indicated USB events
is logged in a status bit of the Interrupt Register. Corresponding bits in the Interrupt
Enable Register determine whether or not an event will generate an interrupt.
Interrupts can be masked globally by means of the INTENA bit of the Mode Register
(see
Table 19
).
The active level and signalling mode of the INT output is controlled by the INTPOL
and INTLVL bits of the Hardware Configuration Register (see
Table 21
). Default
settings after reset are active LOW and level mode. When pulse mode is selected, a
pulse of 166 ns is generated when the OR-ed combination of all interrupt bits
changes from logic 0 to logic 1.

EP0OUT
BUSTATUS
A logic 1 indicates the interrupt source: control OUT endpoint.
It monitors the current USB bus status (0 = awake,
1 = suspend).
A logic 1 indicates that an EOT interrupt has occurred for a short
packet.
A logic 1 indicates that an interrupt is issued every 1 ms
because of the Pseudo SOF; after 3 missed SOFs ‘suspend’
state is entered.
A logic 1 indicates that a SOF condition was detected.
A logic 1 indicates that an internal EOT condition was generated
by the DMA Counter reaching zero.
A logic 1 indicates that an ‘awake’ to ‘suspend’ change of state
was detected on the USB bus.
A logic 1 indicates that a ‘resume’ state was detected.
A logic 1 indicates that a bus reset condition was detected.
