The TCVOPE control bit reset state is defined in Table 59.
When the non-segmented V

The TCVOPE command is also used to read back the temperature via the interface; see Section 6.2.44.

The Internal/external oscillator (EC) command selects the internal or external oscillator. When an external oscillator is
used the external clock signal has to be connected to the OSC pad; see Section 7.6.
The EC control bit reset state is defined in Table 61.
