2.8.4.5 Polling Cycle Calibration

The ATA8510/15 offers a calibration procedure to ensure high accuracy of the adjusted polling cycle. The polling cycle is calibrated after the power-on when the SRC bit is preselected in the eepConfValid.confInitFlags EEPROM setting.

This procedure can be done periodically as a sub-task of the system self-check and calibration. This applies only if the clock source of Timer1 is set to SRC. The EN_SRCCAL bit in the calConf1 EEPROM setting must be set in order to enable the polling cycle calibration during the system self-check and calibration procedure.

Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0

The polling cycle calibration requires additional time. For more information about the polling cycle calibration, see Tune and Check.
