XO 29 O — Crystal output. This pin is the crystal output for the internal oscillator. If the XI pin is driven by an external oscillator, this pin may be left unconnected. When using a crystal, a 1-M Ω feedback resistor is required between the XI and XO pins. USB UPSTREAM SIGNALS USB_DM_UP 22 I/O — USB high-speed differential transceiver (negative) USB_DP_UP 21 I/O — USB high-speed differential transceiver (positive) USB_R1 32 I — Precision resistor reference. Connect a 9.53-k Ω ±1% resistor between the USB_R1 pin and ground. USB_VBUS 16 I — USB upstream port power monitor. The VBUS detection requires a voltage divider. The signal USB_VBUS must be connected to VBUS through a 90.9-k Ω ±1% resistor and to ground through a 10-k Ω ±1% resistor from the signal to ground. USB DOWNSTREAM SIGNALS OVERCUR1z 14 I PU USB port 1 overcurrent detection. This pin is used to connect the overcurrent output of the downstream port power switch for port 1. 0 = An overcurrent event occurred. 1 = An overcurrent event has not occurred. This pin can be left unconnected if power management is not implemented. If power management is enabled, the necessary external circuitry should be determined by the power switch. OVERCUR2z 15 I PU USB port 2 overcurrent detection. This pin is used to connect the overcurrent output of the downstream port power switch for port 2. 0 = An overcurrent event occurred. 1 = An overcurrent event has not occurred. If power management is not implemented, leave this pin unconnected. If power management is enabled, the necessary external circuitry should be determined by the power switch. OVERCUR3z 12 I PU USB port 3 overcurrent detection. This pin is used to connect the overcurrent output of the downstream port power switch for port 3. 0 = An overcurrent event occurred. 1 = An overcurrent event has not occurred. This pin can be left unconnected if power management is not implemented. If power management is enabled, the necessary external circuitry should be determined by the power switch. OVERCUR4z 11 I PU USB port 4 overcurrent detection. This pin is used to connect the overcurrent output of the downstream port power switch for port 4. 0 = An overcurrent event occurred. 1 = An overcurrent event has not occurred. This pin can be left unconnected if power management is not implemented. If power management is enabled, the necessary external circuitry should be determined by the power switch. PWRCTL1/BATEN1 4 I/O PD USB port 1 power-on control for downstream power and battery charging enable. The pin is used for control of the downstream power switch for port 1. The value of the pin is sampled at the deassertion of reset to determine the value of the battery charging support for port 1 as indicated in the Battery Charging Support Register: 0 = Battery charging not supported 1 = Battery charging supported PWRCTL2/BATEN2 3 I/O PD USB port 2 power-on control for downstream power and battery charging enable. The pin is used for control of the downstream power switch for port 2. The value of the pin is sampled at the deassertion of reset to determine the value of the battery charging support for Port 2 as indicated in the Battery Charging Support Register: 0 = Battery charging not supported 1 = Battery charging supported |
