the 31 bit word in the next available position of the FIFO. If TX/R,
the transmitter ready flag is high (FIFO empty), then 8 words,
each 31 bits long, may be loaded. If TX/R is low, then only the
available positions may be loaded. If all 8 positions are full, the

When ENTX goes high, enabling transmission, the FIFO
positions are incremented with the top register loading into the
data transmission shift register. Within 2.5 data clocks the first
data bit appears at either 429DO or

The parity generator counts the ONES in the 31-bit word. If the

The two receivers are independent of the transmitter. Therefore,

onlyrestrictionsare:
1. The received data may be overwritten if not retrieved
withinoneARINCwordcycle.
2. The FIFO can store 8 words maximum and ignores
