9.2.13
An Acknowledge sequence is enabled by setting the
Acknowledge
(SSPCON2<4>). When this bit is set, the SCL pin is
pulled low and the contents of the Acknowledge data bit
is presented on the SDA pin. If the user wishes to gen-
erate an Acknowledge, the ACKDT bit should be
cleared. If not, the user should set the ACKDT bit
before starting an Acknowledge sequence. The baud
rate generator then counts for one rollover period
