8.2.13
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
generate an acknowledge, then the AKDT bit should be
cleared. If not, the user should set the AKDT bit before
starting an acknowledge sequence. The baud rate
generator then counts for one rollover period (T
and the SCL pin is de-asserted (pulled high). When the
SCL pin is sampled high (clock arbitration), the baud
