<Note> AKM cannot assure the period of the data retention (10years [min.] at 85°C) for ‘The unused bits’.
<Note> Kindly pay attention when writing the data for RINT, because EINT also retains the data for RATRM
register written at AKM.
2 Serial Interface
In “Training mode”, it is able to execute the access to the EEPROM and the registers and to input the operational
command for AK2570 with the 32bits serial data via 4pins consist of CS(#12), SK(#13), DI(#14) and DO(#15).
