C Configuration

The S1C17001 incorporates an I
I 2 C module operates as a master device (as single master only) using the clock fed from the 16-bit timer Ch.2. It
supports standard (100 kbps) and fast (400 kbps) modes as well as 7-bit/10-bit slave address mode. It incorporates
a noise filter function to help improve the reliability of data transfers.
This module is capable of generating two different types of interrupts (transmit buffer empty and receive buffer full
interrupts) for easy and continuous processing of serial data transfers with interrupts.
