LOTNUM2 - Lot Number Register 2
LOTNUM3- Lot Number Register 3
LOTNUM0, LOTNUM1, LOTNUM2, LOTNUM3, LOTNUM4 and LOTNUM5 contains the LOT
number for each device. Together with the wafer number and wafer coordinates this gives an
unique identifier or serial number for the device.
• Bit 7:0 - LOTNUM0[7:0] - LOT Number Byte 0
This byte contains byte 0 of the LOT number for the device.
• Bit 7:0 - LOTNUM1[7:0] - LOT Number Byte 1
This byte contains byte 1 of the LOT number for the device.
• Bit 7:0 - LOTNUM2[7:0] - LOT Number Byte 2
This byte contains byte 2 of the LOT number for the device.
• Bit 7:0 - LOTNUM3[7:0] - LOT Number Byte 3
This byte contains byte 3 of the LOT number for the device.
