15.4.7
A Repeated START condition occurs when the RSEN
bit (SSPCON2 register) is programmed high and the
I
bit is set, the SCL pin is asserted low. When the SCL
pin is sampled low, the baud rate generator is loaded
with the contents of SSPADD<5:0> and begins count-
ing. The SDA pin is released (brought high) for one
baud rate generator count (T
generator times out, if SDA is sampled high, the SCL
pin will be de-asserted (brought high). When SCL is
sampled high, the baud rate generator is re-loaded with
the contents of SSPADD<6:0> and begins counting.
SDA and SCL must be sampled high for one T
This action is then followed by assertion of the SDA pin
(SDA = 0) for one T
this, the RSEN bit (SSPCON2 register) will be automat-
ically cleared and the baud rate generator will not be
reloaded, leaving the SDA pin held low. As soon as a
START condition is detected on the SDA and SCL pins,
the S bit (SSPSTAT register) will be set. The SSPIF bit
will not be set until the baud rate generator has
timed-out.

Immediately following the SSPIF bit getting set, the
user may write the SSPBUF with the 7-bit address in
7-bit mode, or the default first address in 10-bit mode.
After the first eight bits are transmitted and an ACK is
received, the user may then transmit an additional
eight bits of address (10-bit mode) or eight bits of data
(7-bit mode).

If the user writes the SSPBUF when a Repeated
START sequence is in progress, the WCOL is set and
the contents of the buffer are unchanged (the write
doesn’t occur).
