9.2.4
While in SLEEP mode, the I
receive addresses or data. When an address match or
complete byte transfer occurs, it wakes the processor
from SLEEP (if the SSP interrupt bit is enabled).
9.2.5
A RESET disables the MSSP module and terminates
the current transfer.

9.2.6
Master mode operation supports 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
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.
The following events will cause SSP Interrupt Flag bit
(SSPIF) to be set (SSP Interrupt, if enabled):
• START condition
• STOP condition
• Data transfer byte transmitted/received
• Acknowledge transmit
• Repeated START
