Table 9-1.
The ATR0622P is an ESD sensitive device.
Observe precautions for handling.
Table 10-1.
The LDO18 is a built in low dropout voltage regulator which can be used if the host system does
not provide the core voltage VDD18.
Table 11-1.
For well-defined start up of LDO18, LDO_IN needs to be connected to LDOBAT_IN.
