4.14.12
WAFNUM – Wafer Number register
• Bit 7:0 – WAFNUM[7:0]: Wafer Number
This byte contains the wafer number for each device. Together with the lot number and wafer
coordinates this gives a serial number for the device.
4.14.13
COORDX0 – Wafer Coordinate X register 0
COORDX0, COORDX1, COORDY0 and COORDY1 contain the wafer X and Y coordinates for
each device. Together with the lot number and wafer number this gives a serial number for each
device.
• Bit 7:0 – COORDX0[7:0]: Wafer Coordinate X Byte 0
This byte contains byte 0 of wafer coordinate X for the device.
4.14.14
COORDX1 – Wafer Coordinate X register 1
• Bit 7:0 – COORDX0[7:0]: Wafer Coordinate X Byte 1
This byte contains byte 1 of wafer coordinate X for the device.
4.14.15
COORDY0 – Wafer Coordinate Y register 0
• Bit 7:0 – COORDY0[7:0]: Wafer Coordinate Y Byte 0
This byte contains byte 0 of wafer coordinate Y for the device.
