The possibility to change the value of OSCCAL during the Oscillator operation allows for in-situ
calibration of the slave node to entering Master frames. The principle of operation is to measure
the TBit during the SYNCH Byte and to change the calibration value of OSCCAL to recover from
local frequency drifts due to local voltage or temperature deviation. The algorithm used for the
synchronization of the internal RC oscillator is depicted in Figure 26-3
