C™ Operation
The MSSP module in I
eral call support) and provides interrupts on start and stop bits in hardware to determine a free
bus (multi-master function). The SSP module implements the standard mode specifications as
well as 7-bit and 10-bit addressing.
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.
