SF (Sinc Filter Register)
The number in this register sets the decimation factor and thus
the output update rate for the primary and auxiliary ADCs. This
SFR cannot be written by user software while either ADC is active.
The update rate applies to both primary and auxiliary ADCs and
is calculated as follows:
1
3

=

where:
f
ADC
= ADC Output Update Rate
f
MOD
= Modulator Clock Frequency = 32.768 kHz
SF
= Decimal Value of SF Register
The allowable range for
SF
is 0DH to FFH. Examples of
SF
values and corresponding conversion update rates (
f
ADC
) and con-
version times (t
ADC
) are shown in Table VIII. The power-on default
value for the SF Register is 45H, resulting in a default ADC update
rate of just under 20 Hz. Both ADC inputs are chopped to mini-
mize offset errors, which means that the settling time for a single
conversion, or the time to a first conversion result in Continuous
Conversion mode, is 2
t
ADC
. As mentioned earlier, all calibra-
tion cycles will be carried out automatically with a maximum, i.e.,
FFH, SF value to ensure optimum calibration performance. Once
a calibration cycle has completed, the value in the SF Register will
be that programmed by user software.

ICON (Current Sources Control Register)
The icon SFR is used to control and configure the various excitation and burnout current source options available on-chip.
SFR Address D5H
Power-On Default Value 00H

Set by user to enable current source-2 (200
A) to external Pin 3 (P1.2/DAC/IEXC1).
Cleared by user to enable current source-2 (200
A) to external Pin 4 (P1.3/AIN5/IEXC2).
2 I1PIN
*
Current Source-1 Pin Select Bit.
Set by user to enable current source-1 (200
A) to external Pin 4 (P1.3/AIN5/IEXC2).
Cleared by user to enable current source-1 (200
A) to external Pin 3 (P1.2/DAC/IEXC1).
1 I2EN Current Source-2 Enable Bit.
Set by user to turn on excitation current source-2 (200
A).
Cleared by user to turn off excitation current source-2 (200
A).
0 I1EN Current Source-1 Enable Bit.
Set by user to turn on excitation current source-1 (200
A).

A).
*
Both current sources can be enabled to the same external pin, yielding a 400
A current source.
