Port 1 Power
Output
PRTPWR1
O8
Enables power to a downstream USB device
attached to Port 1.
0 = Power disabled on downstream Port 1
1 = Power enabled on downstream Port 1
Port 1 Control
PRTCTL1
OD8/IS
(PU)
When configured as PRTCTL1, this pin functions
as both the Port 1 power enable output
(PRTPWR1) and the Port 1 over-current sense
input (OCS1_N). Refer to the PRTPWR1 and
OCS1_N descriptions for additional information.
Port 1 Battery
Charging
Configuration
Strap
BC_EN1
IS
This strap is used to indicate support of the
battery charging protocol on Port 1. Enabling
battery charging support allows a device on the
port to draw currents per the USB battery
charging specification.
0 = Battery charging is not supported on Port 1
1 = Battery charging is supported on Port 1
See Note 3.4 for more information on
configuration straps.
