Small Frames Dropped
The ’Small Frames Dropped’ interrupt vector is generated, when the
receiver discarded N small frames. The length of small frames is defined
in CONF3.MINFL and the threshold value N is defined in register SFDT.
Channel Number
This bit field identifies the channel for which the information in the
interrupt vector is valid.
Underrun
The ’Underrun’ interrupt vector is generated, when the transmit buffer
was not able to provide data to the protocol machine transmit. If this
happens during transmission of a HDLC or PPP packet, the transmitter
will end the already started data packet with an abort sequence.
Frame End
The ’Frame End’ interrupt vector is generated, when one complete data
packet has been transmitted via serial side.
Channel Number
This bit field identifies the channel for which the information in the
interrupt vector is valid.
