Configuration Register 4 - Address 0x104
This register is used to set the minimum update delta for Lookup Tables 0 and 1. The contents of this register
are used when the lookup table address translation by the ADC is compared against the previous value. The
current value must differ from the previous stored value by the amount in this register in order for the translation
to occur.
Configuration Register 5 - Address 0x105
This register is used to set the consecutive count source for Lookup Table 0 and 1, the alarm count, the auto-
monitor (AM#) lockout, and auto-monitor hold-off timer.

conversions that differ from the previously stored conversion by at least
DELTA 1 (bits 7:4 of Configuration register 4) in order for a new
translation to occur.

Indicates the minimum delta between addresses for Lookup table 0.
0b00 = 0, 0b11 = 3. Note that there must be at least COUNT0
consecutive conversions that differ from the previously stored
conversion by at least Delta 0 (bits 3:0 of Configuration register 4) in
order for a new translation to occur.

ALERT# pin assertion. When this bit is cleared, the ALERT# pin is
asserted by the SML2120 on the first alert event.
1
ALERT# pin assertion. When this bit is set, the ALERT# pin is asserted
by the SML2120 on consecutive alert events.
