Function Outline
After Reset, stand by with TxEWAIT, enter TxStart by NTXENIN = 0 and start output of NTXENOUT
= 0. Then, enter S11 by NTXIND = 000 and start output of data from CMI code symbol 11. (The
ARCNET Message header is NTXIND = 00001111).
When NTXENIN = 1 is detected, supplementary output of 10 bit “0” data (symbol 01) is carried out,
and then terminated.
