I/O D
EEPROM Enable Pin
"H" : Read Device Descriptor, String Descriptor from EEPROM
“L” : Read Device/String Descriptor from internal ROM.
Note that CS,SK,EPDI,EPAO is Hi-Z when EPEN is “L”
EEPROM Select Pin
“L” : 1Kbit Type EEPROM is connected.
“H” : 2Kbit/4Kbit EEPROM is connected
If EEPROM is not used, EPSEL should be tied to DGND.
No Connection
Suspend Status Pin
"L" : Suspend State
"H" : Normal Operation
Reset Pin, Low input makes the chip reset sate.
Schmitt Trigger input.
No Connection
No Connection
USB bus Non-Inverting pin.
Because AK5371 is full speed mode device, 1.5kΩ resistor will
be connected between D+ node to VD.
I/O D
USB bus Inverting Pin.
