Typical values are typical under the recommended operation conditions. Maximum values are maximum values
under the recommended operation conditions.
However, the input pin’s high-level voltage value is VDD33 and the low-level input voltage value is VSS.
This depends on the sampling frequency and firmware. The firmware used in this case requires a processing
load of approximately 150 MHz at a sampling frequency of 48 kHz.

Typical values are typical under the recommended operation conditions. Maximum values are maximum values
under the recommended operation conditions.
However, the input pin’s high-level voltage value is VDD33 and the low-level input voltage value is VSS.
The current consumption increases at higher temperatures.
