5.1. ICAL
The device registers must be configured for the device operation. After device configuration, a calibration
procedure must be performed once a stable clock is applied to the selected CKINn input. The calibration process is
triggered by writing a “1” to bit D6 in register 136. See the Family Reference Manual for details. In addition, after a
successful calibration operation, changing any of the registers indicated in Table 8 requires that a calibration be
performed again by the same procedure (writing a “1” to bit D6 in register 136).
