An example flowchart for processing an end of packet is
shown in Figure 2-22. The chart includes the differences in
processing between the ESCC and NMOS/CMOS version.
In this chart, Tx IP and Underrun/EOM INT can be
processed by interrupts or by polling the registers. Note

Data can be written to Tx FIFO after this point
that this flowchart does not have the procedures for
interrupt handling, such as saving/restoring of registers to
be used in the ISR (Interrupt Service Routine), Reset IUS
command, or return from interrupt sequence.
