Test Modes
•DMA interrupts
The processing device DMA interrupts are:
There is no exception device DMA interrupt.
When written to one, the UDCON.TSTPCKT bit switches the USB device controller in a “test
packet”mode:
The transceiver repeatedly transmit the packet stored in the current bank. TSTPCKT must be
written to zero to exit the “test-packet” mode. The endpoint shall be reset by software after a
“test-packet” mode.
This enables the testing of rise and falling times, eye patterns, jitter, and any other dynamic
waveform specifications.
The flow control used to send the packets is as follows:
To stop the test-packet mode, just write a zero to the TSTPCKT bit.
• The NAKed OUT Interrupt (NAKOUTI)
• The High-bandwidth isochronous IN error Interrupt (HBISOINERRI) if the high-bandwidth
