9.2.14
A STOP bit is asserted on the SDA pin at the end of a
receive/transmit by setting the Stop Sequence Enable
bit, PEN (SSPCON2<2>). At the end of a receive/
transmit, the SCL line is held low after the falling edge
of the ninth clock. When the PEN bit is set, the master
will assert the SDA line low. When the SDA line is sam-
pled low, the baud rate generator is reloaded and
counts down to 0. When the baud rate generator times
out, the SCL pin will be brought high, and one T
(baud rate generator rollover count) later, the SDA pin
will be de-asserted. When the SDA pin is sampled high

Whenever the firmware decides to take control of the
bus, it will first determine if the bus is busy by checking
the S and P bits in the SSPSTAT register. If the bus is
busy, then the CPU can be interrupted (notified) when
a STOP bit is detected (i.e., bus is free).

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