PIC18F87J50 FAMILY
19.4.9
A Repeated Start condition occurs when the RSEN bit
(SSPxCON2<1>) is programmed high and the I
module is in the Idle state. When the RSEN bit is set,
the SCLx pin is asserted low. When the SCLx pin is
sampled low, the Baud Rate Generator is loaded with
the contents of SSPxADD<5:0> and begins counting.
The SDAx pin is released (brought high) for one Baud
Rate Generator count (T
Generator times out, and if SDAx is sampled high, the
SCLx pin will be deasserted (brought high). When
SCLx is sampled high, the Baud Rate Generator is
reloaded with the contents of SSPxADD<6:0> and
begins counting. SDAx and SCLx must be sampled
high for one T
assertion of the SDAx pin (SDAx = 0) for one T
while SCLx is high. Following this, the RSEN bit
(SSPxCON2<1>) will be automatically cleared and the
Baud Rate Generator will not be reloaded, leaving the
SDAx pin held low. As soon as a Start condition is
detected on the SDAx and SCLx pins, the S bit
(SSPxSTAT<3>) will be set. The SSPxIF bit will not be
set until the Baud Rate Generator has timed out.

Immediately following the SSPxIF bit getting set, the
user may write the SSPxBUF 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 SSPxBUF 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).
