11.3.3. SXCfgEn - Configuration enabling register
Writing this register allows enabling or disabling the different configuration register sets.
Note:
11.3.4. SXUpdated - Updated configuration register
The configuration update registers contain which configuration has been updated by a measurement result.
These bits are set to 1 every time a measurement is done on one of the 4 configurations. When the registers are read, these
bits are set back to 0 by the communication engine, the bits 4 to 7 indicates an overflow.
11.3.5. Configuration register - measurement mode
This register is present in each configuration; the bits 0 & 1 are controlling the measurement mode.
The bit SINGLE is set by the user, once the measurement is done; the measurement engine clears the CONF bit of the
configuration.
The bit CONT is set by the user, the measurement is done continuously until this bit is cleared by the user.
