Serial Load Control Registers
The serial load registers are controlled by a three wire
serial interface through the bi-directional parallel port
to reduce the pin count of this device. When SYNCH
is set to high, the output bus is tri-stated and the serial
interface is activated. DB7/LD, DB5/SCLK and DB6/
SDATA are the three input signals that control this
process. The DB7/LD signal is set low to initiate the
loading of the internal registers.
There are internal registers that are accessed via an
11-bit data string. Data is shifted in on the rising edge
of SCLK and loaded to the registers on the rising edge
of LD.
The data on pin
DB6/SDATA is latched
automatically after eleven DB5/SCLKs have been
counted. If eleven clocks are not present on DB5/
SCLK before the DB7/LD signal returns high, no data
will be loaded into the internal registers. If more than
11 clocks are present on DB5/SCLK, the additional
clocks will be ignored. The data corresponding to the
first eleven DB5/SCLKs will be loaded only.
The first three MSBs choose which internal register will
be selected. The remaining 8 LSBs contain the data
needed for programming the internal register for a
particular configuration.
Power-Up State of the Internal Registers
The control register settings upon initial power-up are
for CIS, DC Coupled configuration (VRT is set to
internal, Input DC Reference=AGND and the input to
the ADC is selected through the RED channel). Gain
is unity and Offset is set to zero. The test modes are
disabled in the power-up state.
