15.2.5
Master mode of operation is supported by interrupt
generation on the detection of the START and STOP
conditions. The STOP (P) and START (S) bits are
cleared from a RESET, or when the MSSP module is
disabled. Control of the I
P bit is set, or the bus is idle, with both the S and P bits
clear.
In Master mode, the SCL and SDA lines are manipu-
lated by the MSSP hardware.
