EEPROM Data Structure
EEPROM contains hardware configuration information. After reset by RN, the UVCD reads the EEPROM and
uses the information to configure the chip. The first four bytes of the EEPROM are Key to the EEPROM. If
the EEPROM is absent or the Key is invalid, the UVCD is configured with a set of default values.

Chip Configuration Low Byte
D[7] Class audio or vendor audio
0 – Inform the host that the chip is USB audio class device
1 – Inform the host that the chip is vendor specific audio device
D[6] USB audio class volume control capability when audio source is I2S device.
When audio source is AC97, the chip is always capable of volume control
regardless of the state of this bit.
0 – Inform the host that the chip is not capable of volume control.
1 – Inform the host that the chip is capable of volume control.
D[5:4] Audio Configuration
00 – No audio on board.
01 – AC97 audio on board with 5 sample rates: 48K, 44.1K, 32K, 16K, and 8K.
10 – I2S audio on board with 3 sample rate: 32K, 16K, and 8K.
11 – I2S audio on board with 5 sample rates: 48K, 44.1K, and 32K, 16K, and 8K.
D[3] USB Remote Wakeup Capable when set to 1
D[2] USB Self Power Capable when set to 1. If the chip is configured to be Self Power
Capable, PIO7 becomes self power status input.
D[1:0] USB Max Power Select
00 – USB Max Power 500 mA
01 – USB Max Power 400 mA
10 – USB Max Power 300 mA
11 – USB Max Power 200 mA
Chip Configuration High Byte
D[7:5] Reserved. Set to 0.
D[4] Transport stream on board
0 – Inform the host that the chip supports transport stream.
1 – Inform the host that the chip does not support transport stream.
D[3:2] Transport stream iso-chronous request interval
00 – Inform the host that request interval is 0 (one request every micro-frame)
01 – Inform the host that request interval is 1 (one request every 2 micro-frames)
10 – Inform the host that request interval is 2 (one request every 4 micro-frames)
11 – Inform the host that request interval is 3 (one request every 8 micro-frames)
D[1:0] Transport stream MaxPacketSize select
00 – Inform the host that MaxPacketSize is 188*1 bytes
01 – Inform the host that MaxPacketSize is 188*2 bytes
10 – Inform the host that MaxPacketSize is 188*3 bytes
11 – Inform the host that MaxPacketSize is 188*4 bytes
