DATA_AV TYPE
Bit 4 and bit 5 (DATA_T, DATA_P) of control register 1 are used to program the signal DATA_AV. Bit 4 of control register 1
determines whether the DATA_AV signal is static or a pulse. Bit 5 of the control register determines the polarity of
DATA_AV. This is shown in Table 14.

The signal DATA_AV is set to active when the trigger condition is satisfied. It is set back inactive dependent of the DATA_T
selection (pulse or level).
If level mode is chosen, DATA_AV is set inactive after the first of the TL (TL = trigger level) reads (with the falling edge of
READ). The trigger condition is checked again after TL reads. For single conversion mode, DATA_AV type should be
programmed to active level mode (set bit 4 of CR1 to zero).
If pulse mode is chosen, the signal DATA_AV is a pulse with a width of one half of a CONV_CLK cycle in continuous
conversion mode. The next DATA_AV pulse (when the trigger condition is satisfied) is sent out the earliest, when the TL
values, written into the FIFO before, were read out by the processor.
