Acknowledge Sequence Timing
An acknowledge sequence is enabled by setting the acknowledge sequence enable bit, ACKEN
(SSPCON2<4>). When this bit is set, the SCL pin is pulled low and the contents of the acknowl-
edge data bit is presented on the SDA 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 baud rate generator then counts for one rollover period (T
the SCL pin is de-asserted (pulled high). When the SCL pin is sampled high (clock arbitration),
the baud rate generator counts for T
ACKEN bit is automatically cleared, the baud rate generator is turned off, and the SSP module
then goes into IDLE mode
If the user writes the SSPBUF when an acknowledge sequence is in progress, then WCOL is set
and the contents of the buffer are unchanged (the write doesn’t occur).
