Transmit S
The ’Transmit S
XSAW1 - XSAW3 has been sent N times, where N is defined prior to
transmission in XSAW3.XSAV.
All Sent
The ’All Sent’ interrupt vector is generated, when the last bit of a frame
to be transmitted is completely sent out and XFF.XFIFO is empty.
Transmit Data Underrun
The ’Transmit Data Underrun’ interrupt vector is generated, when the
transmit FIFO runs out of data during transmission of a frame. The
signalling controller terminates the affected frame with an abort
sequence.
Transmit Pool Ready
The ’Transmit Pool Ready’ interrupt vector is generated, when a new
data block of up to 32 bytes can be written to transmit FIFO. ’Transmit
Pool Ready’ is the fastest way to access the transmit FIFO. It has to be
used for transmission of long frames, back-to-back frames or frames
with shared flag.
Port Number
0..27 The port number the interrupt vector is associated with.
