18.5.12
An Acknowledge sequence is enabled by setting the
Acknowledge
(SSPxCON2<4>). When this bit is set, the SCLx pin is
pulled low and the contents of the Acknowledge data bit
are presented on the SDAx pin. If the user wishes to
generate an Acknowledge, then the ACKDT bit should
be cleared. If not, the user should set the ACKDT bit
before starting an Acknowledge sequence. The BRG
then counts for one rollover period (T
pin is deasserted (pulled high). When the SCLx pin is
sampled high (clock arbitration), the BRG counts for
T
ACKEN bit is automatically cleared, the BRG is turned
off and the MSSP module then goes into an inactive
state (Figure 18-25).
18.5.12.1
If the user writes the SSPxBUF when an Acknowledge
sequence is in progress, then WCOL is set and the
contents of the buffer are unchanged (the write does
not occur).

18.5.13
A Stop bit is asserted on the SDAx pin at the end of a
receive/transmit by setting the Stop Sequence Enable
bit, PEN (SSPxCON2<2>). At the end of a
receive/transmit, the SCLx line is held low after the
falling edge of the ninth clock. When the PEN bit is set,
the master will assert the SDAx line low. When the
SDAx line is sampled low, the BRG is reloaded and
counts down to 0. When the BRG times out, the SCLx
pin will be brought high and one Baud Rate Generator
rollover count (T
serted. When the SDAx pin is sampled high while SCLx
is high, the Stop bit (SSPxSTAT<4>) is set. A T
later, the PEN bit is cleared and the SSPxIF bit is set
(Figure 18-26).
