C Operation
The SSP module in I
and provides interrupts on start and stop bits in hardware to facilitate software implementations
of the master functions. The SSP module implements the standard and fast mode specifications
as well as 7-bit and 10-bit addressing.
Two pins are used for data transfer. These are the SCL pin, which is the clock, and the SDA pin,
which is the data. The user must configure these pins as inputs through the TRIS bits. The SSP
module functions are enabled by setting SSP Enable bit, SSPEN (SSPCON<5>).
A “glitch” filter is on the SCL and SDA pins when the pin is an input. This filter operates in both
the 100 KHz and 400 KHz modes. In the 100 KHz mode, when these pins are an output, there
is a slew rate control of the pin that is independent of device frequency.
