9.2.14
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
ACKDT (SSPCON2<5>) is presented on the SDA pin.
If the user wishes to generate an Acknowledge (ACK),
then the ACKDT bit should be cleared. Otherwise, the
user should set the ACKDT bit (NACK) before starting
an Acknowledge sequence. The baud rate generator is
then loaded from SSPADD<6:0> and counts for one
rollover period (T
(pulled high). When the SCL pin is sampled high (clock

counts for another T

• The SCL pin is pulled low.
• The ACKEN bit is automatically cleared.
• The baud rate generator is turned off.
• The MSSP module goes into IDLE mode.

If the user writes the SSPBUF when an Acknowledge

tents of the buffer are unchanged (the write doesn’t
occur).
