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.
