Bandgap Reference Circuitry and Powerdown
A Bandgap Reference Circuit provides a temperature stable 1.2V reference voltage for the device.
A power down mode is available to switch off all subcircuits that are controlled by the bidirectional
Powerdown&DataDetect
PwdDD
pin (pin 27) as shown in the following table. Power down mode
can either be activated by pin 27 or bit D14 in Register 00. In power down mode also pin 28 (DATA)
is affected (see
Section 2.4.17
).
