2.11.5 Serial Interface Ports
The I/O ports (P67, P70 to P72) function as I/O ports of UART2 and multi-master I²C-BUS interface 0
(refer to “2.11.6 Multi-master I²C-BUS interface i”) . Set the connection between both serial interfaces
and each port by bits 0 and 1 (BSEL0 and BSEL1) of the peripheral mode register (address 027D16) and
bit 2 (FIICON) of the I²C0 port selection register (address 02E516).
