The user generates a START Condition by set-
ting the START enable bit (SEN) in SSPCON2.
SSPIF is set. The module will wait the required
START time before any other operation takes
place.
The user loads the SSPBUF with address to
transmit.
Address is shifted out the SDA pin until all 8 bits
are transmitted.
The MSSP Module shifts in the ACK bit from the
slave device and writes its value into the
SSPCON2 register (SSPCON2<6>).
The module generates an interrupt at the end of
the ninth clock cycle by setting SSPIF.
The user loads the SSPBUF with eight bits of data.
DATA is shifted out the SDA pin until all 8 bits are
transmitted.
The MSSP Module shifts in the ACK bit from the
slave device, and writes its value into the
SSPCON2 register (SSPCON2<6>).
The MSSP module generates an interrupt at the
end of the ninth clock cycle by setting the SSPIF
bit.
The user generates a STOP condition by setting
the STOP enable bit PEN in SSPCON2.
Interrupt is generated once the STOP condition
is complete.
