5.4 BTPAUSE

BTPAUSE is an optional adjustment to the baseline tracking, which inhibits the baseline tracking operation for the duration of a button press. This functionality applies to the internal data used by the LDC211x and LDC3114 and not just the OUTx pin operation. This can keep a button actuated for a longer time, and also be useful for some applications which post-process data. BTPAUSE can be enabled on all channels or any subset of channels.
