20.5.9
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 BRG is loaded with the contents of
SSPxADD<5:0> and begins counting. The SDAx pin is
released (brought high) for one BRG count (T
When the BRG times out, and if SDAx is sampled high,
the SCLx pin will be deasserted (brought high). When
SCLx is sampled high, the BRG is reloaded with the
contents of SSPxADD<6:0> and begins counting.
SDAx and SCLx must be sampled high for one T
This action is then followed by assertion of the SDAx
pin (SDAx = 0) for one T
Following this, the RSEN bit (SSPxCON2<1>) will be
automatically cleared and the BRG 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 Start bit (SSPxSTAT<3>) will be set. The SSPxIF bit
will not be set until the BRG 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 8 bits
of address (10-bit mode) or 8 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 does
not occur).
