17.6.5.3 Post conditions
After a successful manual spool calibration, the calibration counter and bit inverted copy for spool calibration should be
updated as described below:
• Populate a temporary data sector for “Production/Calibration Flag”. Update the Spool dead-band calibration
counters. Increment P3771 from 0 to 1 and increment bit-wise inverted P3772 from 255 to 254 for the displayed
below,

• Calculate the sector CRC as CRC-16-CCITT (P3771…P3778) and store (word) at the CRC/Checksum address
(P3789). For example of how to calculate sector CRC, please see paragraph 17.5.2
• Write data sector “Production/Calibration Flag” to the MAIN-controller
