USB INTERRUPTS
The USB module is capable of generating interrupts and causing the CPU to
execute the USB interrupt service routine. There are three types of USB
interrupts:
UE0D0
$0020
UE0D7
$0027
UE1D0
$0028
UE1D7
$002F

These read only bits store the number of data bytes received for the last OUT
or SETUP transaction for Endpoint 0. These bits are not affected by reset.
These read only bits are serially loaded with OUT token or SETUP token data
received over the USB’s D+ and D– pins.
These write only buffers are loaded by software with data to be sent on the
USB bus on the next IN token directed at Endpoint 0.
These write only buffers are loaded by software with data to be sent on the
USB bus on the next IN token directed at Endpoint 1 or Endpoint 2. These buff-
ers are shared by Endpoints 1 and 2 and depend on proper configuration of the
ENDADD bit.
