Note 4. The power up sequence between AVDD, DVDD and CVDD is not critical.
In slave mode, the AK5367 must be power up at the PDN pin = “L”.
In master mode, the AK5367 must be power up at the PDN pin = “L”, or when DVDD is powered up, MCLK
clock must input and the AK5367 must be reset by the PDN pin=“L”. The internal register data is unknown until
PDN pin=“L”. The power on/off sequence between AVDD, DVDD and CVDD is not critical, however when
DVDD is powered off, all digital input pins must be left floating or held to VSS.
The power off is means that AVDD, CVDD and DVDD are floating or short to VSS.
WARNING: AKEMD assumes no responsibility for the usage beyond the conditions in this datasheet.
