Input/Output Pins
Table 13.1 summarizes the input/output pins used by the I
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.
