COORDX1 - Wafer Coordinate X Register 1
COORDY0 - Wafer Coordinate Y Register 0
COORDY1 - Wafer Coordinate Y Register 1
ADCACAL0 - ADCA 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
ADCACAL0 and ADCACAL1 contains the calibration value for the Analog to Digital Converter A
(ADCA). Calibration of the Analog to Digital Converters are done during production test of the
device. The calibration bytes are not loaded automatically into the ADC calibration registers, and
this must be done from software..
• Bit 7:0 - ADCACAL0[7:0] - ADCA Calibration Byte 0
This byte contains byte 0 of the ADCA calibration data, and must be loaded into the ADCA CALL
register.
