TIGER560 ETC, TIGER560 Datasheet - Page 14

• Manufacturer Part Number: TIGER560
• Description: USB Controller for Low Cost VoIP solutions
• Manufacturer: ETC

USB vendor and product I.D.s
The USB vendor and product I.D.s are set by pull-up and pull down resistors on the following
pins.
Vendor I.D. bits 0 – 7 on SRAM data bus SDA0 – SDA7
Vendor I.D. bits 8 – 15 on PIB data bus HD0 – HD7
Product I.D. bits 0 – 14 on SRAM address bus SAD0 – SDA14
Product I.D. bit 15 on PIB address HA0
On reset the inputs are read into internal registers, it is important to ensure that peripheral
devices connected to these inputs tri-state their outputs on reset.
