Table 13.1 summarizes the input/output pins used by the I

2

C bus interface. The serial clock I/O pin 

for each channel can be selected from the three pins*. The serial data I/O pin for each channel can 
be selected form the three pins*. Do not set multiple pins as the serial clock I/O pin or serial data 
I/O pin for a single channel. 

Note:  * 

The program development tool (emulator) does not support this function.
