Address Inputs
AD0 - LSB
AD3 - MSB
These four signals provide the address codes that control the
operation of the interface.
A10 IN is the address input to the internal RAM.
A10 OUT buffered TX/RX bit when tied to A10 IN segregates the
2k by 16 RAM into two 1k by 16 blocks of memory: one for
Receive, the other for Transmit Data.
Broadcast Enable. When low, the recognition of Broadcast
Command is prevented on the specified bus.
Built-ln Test Decode. When held low, prevents resetting TXTO
Bit, HSFAIL Bit, and LTFAIL Bit in the Bit Word (as well as TF
and SSF Bits in the Status Word) upon receipt of a Transmit Bit
Word Mode Command.
Buffer Empty Flag - goes low when the output FIFO Buffer is
empty. Will transition to the high state when the first word
appears in the Buffer.
