nAutoFd/HostBusy/HostAck
Compatibility mode: Not used.
negotiation phase: In order to request 1284 mode, this signal is set low and
IEEE 1284active (nSelectln) is set high. Afterwards, this signal is set high
when PtrClk (nAck) is set low.
reverse data transfer phase: In nibble mode, setting this signal low
indicates to the printer that the host is ready to receive data. When this
signal is subsequently set high, it indicates that the host received the data.
reverse idle phase: This signal is set high in response to a PtrClk (nAck)
low pulse in order to return to the reverse data phase. If this signal is set
high at the same time that IEEE 1284active (nSelectln) is set low the IEEE
1284 idle phase is aborted and the interface returns to compatibility mode.
ECP mode: Used for reverse direction flow control. Also used for
handshaking via PeriphClk (nAck).
NC
Not used.

Parallel B: NC.
Parallel C: Pull up to +5V with 3.9 K

.
nlnit/nReverseRequest
Compatibility mode: When a low signal is detected, the printer is deemed
to be BUSY until the low signal is released.
negotiation phase: Always high.
reverse data transfer phase: Always high.
ECP mode: Low when switching to reverse direction. The peripheral
device has permission to drive the data signals only when this signal is
low and 1284active is high.
