LINTI1

LBI Interrupt Input from Peripheral1

In case of bit HE1 in register LCONF is

set (HSCX register decoding selected)

this pin must be connected to VDD3 if

unused.

In case of bit HE1 in register LCONF is

reset (ESCC2 register decoding

selected) this pin must be connected

to VSS if unused.
