(1) I²Ci port selection register (i = 0, 1)
The I²Ci port selection register consists of bit to validate the multi-master I²C-BUS interface i function.
s Bit 2: Multi-master I²C-BUS interface valid bit (FIICON)
When this bit is “0,” the multi-master I²C-BUS interface i is nonactive; when “1,” it is active. When
selecting active, multi-master I²C-BUS interface 0 is connected with the ports selected by bits 0 and 1
of the peripheral mode register (address 027D16) and multi-master I²C-BUS interface 1 is connected
with the ports P93 and P94.
Note: It needs 10-BCLK cycles from setting this bit to “1” to being active of multi-master I²C-BUS
interface i. Accordingly, do not access multi-master I²C-BUS interface i-related registers in this
period.
