DESCRIPTION
Terminal functions DATA-DR^†,
FSD^†, D11OUT, and D10OUT
are applicable in this
configuration. FSD is asserted
during secondary
communication, but 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 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.
