USB_CALIB[16:11] USB pad HS_CURR_LEVEL[5:0] for Port 1

USB_CALIB[22:17] USB pad HS_CURR_LEVEL[5:0] for Port 2

USB_CALIB[28:23] USB pad HS_CURR_LEVEL[5:0] for Port 3

3. Calculate the offset from fused HS_CURR_LEVEL value and desired value from Step 1.

a). For example, if default value is 0x20 and desired value is 0x1C, then offset = -4

b). For example, if default value is 0x10 and desired value is 0x14, then offset = +4

Note: Maximum allowable offset: ±6 steps.

4. Provide the "tuned offset value" to software team so they can add the offset value when

initializing the registers in Table 2.

Software Verification

NVIDIA strongly recommends a functional check. Connect the DUT to USB hosts and devices

to perform a functional check.

To check if software has implemented the tuned offset correctly, load new software with offset

included into another DUT and make sure that:

HS_CURR_LEVEL = USB_CALIB fuse + tuned offset steps.
