Second Serial Interface Configuration J13, J14
Jumpers J13 and J14 enable selection of the signal source of the
second serial interface. As an alternate to the software-emulated
interface at port pins P3.0 and P3.1 of the controller, an optional
external UART can be installed on the phyCORE-167CR/167CS at
U7. With the implementation of the external UART, the port pins can
be used as standard I/O pins at X1A44 (P3.0) and X1A45 (P3.1).
The following configurations are possible:

J15 Address of the Serial EEPROM/ FRAM
Jumper J15 configures the serial EEPROM/FRAM address. The
default configuration (J15 = 2+3) sets the address to 0xA8.
The following configurations are possible:
