11.34 Interrupts
The USB module uses interrupts to signal USB events
such as a change in status, data received and buffer
empty events, to the CPU. Software must be able to
respond to these interrupts in a timely manner.
11.35 Interrupt Control
Each interrupt source in the USB module has an inter-
rupt flag bit and a corresponding enable bit. In addition,
the UERRIF bit (U1IR<1>) is a logical OR of all the
enabled error flags and is read-only. The UERRIF bit
can be used to poll the USB module for events while in
an Interrupt Service Routine (ISR).
11.36 USB Module Interrupt Request
Generation
The USB module can generate interrupt requests from
a variety of events. To interface these interrupts to the
CPU, the USB interrupts are combined such that any
enabled USB interrupt will cause a generic USB inter-
rupt (if the USB interrupt is enabled) to the interrupt
controller, see Figure 11-11. The USB ISR must then
determine which USB event(s) caused the CPU inter-
rupt and service them appropriately. There are two lay-
ers of interrupt registers in the USB module. The top
level of bits consists of overall USB status interrupts in
the U1OTGIR and U1IR registers. The U1OTGIR and
U1IR bits are individually enabled through the corre-
sponding bits in the U1OTGIE and U1IE registers. In
addition, the USB Error Condition bit (UERRIF) passes
through any interrupt conditions in the U1EIR register
enabled via the U1EIE register bits.
11.37 Interrupt Timing
Interrupts for transfers are generated at the end of the
transfer. Figure 11-10 shows some typical event
sequences that can generate a USB interrupt and
when that interrupt is generated. There is no mecha-
nism by which software can manually set an interrupt
bit.
The values in the Interrupt Enable registers (U1IE,
U1EIE, U1OTGIE) only affect the propagation of an
interrupt condition to the CPU’s interrupt controller.
Even though an interrupt is not enabled, interrupt flag
bits can still be polled and serviced.
11.38 Interrupt Servicing
Once an interrupt bit has been set by the USB module
(in U1IR, U1EIR or U1OTGIR), it must be cleared by
software by writing a ‘1’ to the appropriate bit position
to clear the interrupt. The USB Interrupt, USBIF
(IFS1<25>), must be cleared before the end of the ISR.
