Terminal functions DATA-DR,
FSD, D11OUT, and D10OUT are
applicable in this configuration.
FSD is asserted during
secondary communication, but
the FSR is not asserted.
However, FSD remains high
during primary communication.
Terminal functions DATA-DR,
FSD, D11OUT, and D10OUT are
applicable in this configuration.
FSD is asserted during
secondary communication, but
the FSR is not asserted.
However, FSD remains high
during primary communication. If
secondary communications occur
while the A/D conversion is being
transmitted from DR, FSD cannot
go low, and data from DATA-DR
cannot go onto DR.
Terminal functions CONTROL,
WORD-BYTE, EODR, and
EODX are applicable in this
configuration.
