SC66 Hardware Design
When Micro USB is
used, it can be used as
USB_ID pin.
When USB Type-C is
used, it should be
connected to
VPH_PWR through a
10KΩ resistor;
1)
When uUSB
is used,
it should be connected
to GND through a
10KΩ resistor.
Cannot be multiplexed
into a general-purpose
GPIO.
When USB Type-C is
used, it should be
connected to
SS_DIR_OUT;
When uUSB is used, it
should be connected to
GND.
Cannot be multiplexed
into a general-purpose
GPIO.
Comment
Active Low.
Require external
pull-up to 1.8V.
If unused, keep it
open.
Cannot be multiplexed
into general-purpose
GPIOs.
