5.1.3 Analog Control Registers
The Analog Register Block also contains a
Power Con-
figuration Register; Table 14
, and a
Reset Control Reg-
ister; Table 15
.
The
Power Configuration Register
controls the internal
analog functionality that directly effect power consump-
tion of the device. An external precision resistor pin is
available on the MCM20014 that may be used to more
accurately regulate the internal current sources. This
serves to minimize variations in power consumption that
are caused by variations in internal resistor values as
well as offer a method to reduce the power consumption
of the device. The default for this control uses the inter-
nally provided resistor which is nominally 12.5k
. This
feature is enabled by setting the
res
bit of the
Power
Configuration Register
and placing a resistor between
the pin; EXTRES, and ground.
Figure 14
depicts the
power savings that can be achieved with an external re-
sistor at a specific clock rate. Power is further reduced
at lower clock rates.
The databus output; ADC[9:0], is tristated using the
Power Configuration Register
by setting the
dbt
bit.
The MCM20014 is put into a standby mode via the I
2
C
interface by setting the
sby
bit of the
Power Configura-
tion Register
.
