Description
crystal oscillator input (6 MHz)
crystal oscillator output (6 MHz)
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset; connect to V
(internal POR circuit)
supply voltage; connect to USB supply V
ground supply
regulated supply voltage (3.3 V
regulator; used to connect pull-up resistor on UP_DP line;
pin function is controlled via the Device Status Register
(see
Connect = 0 — V
Connect = 1 — V
upstream port D connection (analog)
upstream port D connection (analog)
downstream port 1 D connection (analog)
downstream port 1 D connection (analog)
downstream port 2 D connection (analog)
downstream port 2 D connection (analog)
power switch control output for downstream port 1
(open-drain)
power switch control output for downstream port 2
(open-drain)
pin function is controlled via the USBCON register (see
Table
EnableOverCurrent = 0 — GoodLink LED indicator output
for downstream port 1 (analog, open-drain); to connect an
LED use a 330
EnableOverCurrent = 1 — overcurrent sense input for
downstream port 1 (analog or digital); overcurrent sensing
can be either analog (AnalogOCDisable = 0) or digital
(AnalogOCDisable = 1)
pin function is controlled via the USBCON register (see
Table
EnableOverCurrent = 0 — GoodLink LED indicator output
for downstream port 2 (analog, open-drain); to connect an
LED use a 330
EnableOverCurrent = 1 — overcurrent sense input for
downstream port 2 (analog or digital); overcurrent sensing
can be either analog (AnalogOCDIsable = 0) or digital
(AnalogOCDisable = 1)
