COORDX1 – Wafer Coordinate X Register 1
COORDY0 – Wafer Coordinate Y Register 0
COORDY1 – Wafer Coordinate Y Register 1
USBCAL0 – USB Calibration Register 0
• Bit 7:0 – COORDX0[7:0]: Wafer Coordinate X Byte 1
This byte contains byte 1 of wafer coordinate X for the device.
• Bit 7:0 – COORDY0[7:0]: Wafer Coordinate Y Byte 0
This byte contains byte 0 of wafer coordinate Y for the device.
• Bit 7:0 – COORDY1[7:0]: Wafer Coordinate Y Byte 1
This byte contains byte 1 of wafer coordinate Y for the device
USBCAL0 and USBCAL1 contain the calibration value for the USB pins. Calibration is done dur-
ing production to enable operation without requiring external components on the USB lines for
the device. The calibration bytes are not loaded automatically into the USB calibration registers,
so this must be done from software.
• Bit 7:0 – USBCAL0[7:0]: USB Pad Calibration Register 0
This byte contains byte 0 of the USB pin calibration data, and must be loaded into the USB
CALL register.
