5.1. ICAL
The device's registers must be configured for the intended applications. After the part is configured, the part must
perform a calibration procedure when there is a stable clock on the selected CLKINn 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 12 requires that a calibration be
performed again by the same procedure (writing a "1" to bit D6 in register 136).
