GPIO7:0 Wakeup Enables
Bit x = 0 -> GPIOx pin disabled for wakeup use.
Bit x = 1 -> GPIOx pin enabled for wakeup use.
1Fh
GPIO10:8 Wakeup Enables
Bit x = 0 -> GPIO(x+8) pin disabled for wakeup use.

Note:
The descriptor type for the device descriptors specified in the EEPROM is a don't care and
always overwritten by HW to 0x1.
The descriptor size for the device descriptors specified in the EEPROM is a don't care and
always overwritten by HW to 0x12.
The descriptor type for the configuration descriptors specified in the EEPROM is a don't care
and always overwritten by HW to 0x2.
Note: Descriptors specified in EEPROM having bcdUSB, bMaxPacketSize0, and bNumConfigu-
rations fields defined with values other than 0200h, 40h and 1, respectively, will result in
unwanted behavior and untoward results.
Note: EEPROM byte addresses past 20h can be used to store data for any purpose.
