78M6610+PSU Data Sheet
The routine X-Y compensation coefficient calibration, utilizes both measured voltage and frequency and
the target current measured using an external power meter as in Figure 15.
To start the command, the user writes the calibration command, setting bits XYR and I, and other needed
options such as line-lock. On completion, the XYcomp parameter will be written with an estimate for the
bulk capacitance. Once completed, the calibration routines will store the new gain coefficients in the
relevant registers. During the calibration process, each input is accumulated over the entire calibration
interval as specified by the CalCycs register.
This routine is not recursive; the user may need to re-issue the calibration command until the current
reading matches the target current.
After completion of the calibration, in order to save the new coefficients into flash memory as defaults, it is
necessary to issue the Access (ACC) Command.

Figure 14: Typical Calibration Setup
2.13.4 On-Chip Temperature Calibration
To calibrate the on-chip temperature sensor, the user must first write only the “T” command bit to a “1” (all
other bits 0). This command prevents the firmware from overwriting TempC register. Next the user must
write the known chip temperature to TempC. Finally the user writes the Calibration Command to
0xCA0400 (Calibrate Temperature). This will cause the Toffs parameter to be updated with a new offset
based on the known temperature supplied by the user. In order to save the new coefficients into flash
memory as defaults, it is necessary to issue the Access (ACC) Command.
2.13.5 External Temperature Calibration
To calibrate External Temperature, the user must first write only the “X” command bit to a “1” (all other
bits 0). This prevents the firmware from overwriting ExtTemp. Next the user must write the known external
temperature reading to ExtTemp. Finally the user writes the Calibration Command to 0xCA0100
(Calibrate External Temperature). This will cause the Xgain parameter to be updated with a new gain
based on the known external temperature value supplied by the user. In order to save the new
coefficients into flash memory as defaults, it is necessary to issue the Access (ACC) Command.
