2.6.12 VIDSTA: VID/PID Status Register
This register is used to read the value on four external pins. The firmware can use this value to select one of the vendor
identification/product identifications (VID/PID) stored in memory. The TUSB2136 supports up to 16 unique VID/PIDs
with application code to support different products. This provides a unique opportunity for original equipment
manufacturers (OEMs) to have one device to support up to 16 different product lines by using S0−S3 to select VID/PID
and behavioral application code for the selected product.

BIT NAME RESET FUNCTION
3−0 S[3:0] x VID/PID selection bits. These bits reflect the status of the external pins as defined by Table 2−6. Note that a
pin tied low is reflected as a 0 and a pin tied high is reflected as a 1.
