DESCRIPTION
I/O Selected CC signal as output - connect to CC_IN pin
I
CC Signal select pin input – Connect to CC_SEL_OUT
O CC Signal select pin output – Connect to CC_SEL_IN
I
Active Low CC MUX Enable input – connect to CC_OEn_OUT
Active Low CC MUX Enable output – connect to CC_OEn. The pin is also sampled
I/O
upon reset to set the polarity of the VCTRL1 and VCTRL2.
0 = VCTRL1/2 polarity is active high.
1 = VCTRL1/2 polarity is active low.
I/O USB Type-C configuration channel for position 1
