11.3.3. SXCfgEn - Configuration enabling register
Writing this register allows enabling or disabling the different configuration register sets.
Note:
When the configuration is set to SINGLE, the bit CONFx is cleared automatically after the measurement is done.
Table 24. Configuration enabling register; address 0x02
11.3.4. SXUpdated - Updated configuration register
The configuration update registers contain which configuration has been updated by a measurement result.
Table 25. Updated configuration register; address 0x03
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.
Table 26. Measurement mode in configuration registers; addresses 0x10, 0x30, 0x50, 0x70
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.
