Master Mode
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 SSP
module is disabled. Control of the I
with both the S and P bits clear.
In master mode the SCL and SDA lines are manipulated by the SSP 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
