MB9A110 Series
The number after the underscore ("_") in pin names such as XXX_1 and XXX_2 indicates the relocated
port number. For these pins, there are multiple pins that provide the same function for the same channel.
Use the extended port function register (EPFR) to select the pin.

SOT2_2
(SDA2_2)
Multifunction serial interface ch.2
output pin.
This pin operates as SOT2 when it is
used in a UART/CSIO (operation
modes 0 to 2) and as SDA2 when it is
used in an I
2C (operation mode 4).
