Stop Condition Timing
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 sampled 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
pin is sampled high while SCL is high the P bit (SSPSTAT<4>) is set. A T
is cleared and the SSPIF bit is set
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 the WCOL bit is set
and the contents of the buffer are unchanged (the write doesn’t occur).
