C Master Mode Repeated Start Condition Timing
A Repeated Start condition occurs when the RSEN bit (SSPCON2<1>) is programmed high and
the I
When the SCL pin is sampled low, the baud rate generator is loaded with the contents of
SSPADD<5:0>, and begins counting. The SDA pin is released (brought high) for one baud rate
generator count (T
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

cally cleared, and the baud rate generator is not 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<3>) 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).
Note 1: If RSEN is programmed while any other event is in progress, it will not take effect.
Note 2: A bus collision during the Repeated Start condition occurs if:
