EndPoint1 for SS/HS/FS (EEPROM:08h)

The time interval (named “bInterval”) for polling Interrupt IN endpoint 1 for data transfers of SuperSpeed/High-Speed/Full-Speed is

stored at EEPROM offset 08h. It is expressed in frames or microframes depending on the device operating speed (i.e. either

1 millisecond or 125 μs units).

80h for Full-Speed (the polling time of endpoint 1 = 128 × 1 ms = 128 ms).

Max. Burst for EP3/EP2 (EEPROM: 3Ch)

This value is bMaxBurst field in SS endpoint companion descriptor.

LED Mode (EEPROM: 42h)

LED Mode defines the indication setting for LED_0/1/2/3 function of MFA[0/1/2/3] pins.

Note: Bit 15 must be ‘1’ to enable the LED_mode setting; otherwise, it will work at default LED mode.

The LED mode table is as below:
