RESET
Serial interface RESET input.
12
1
In serial interface mode, the user must initialize internal registers through hardware
RESET by applying a high-going pulse on this pin or by using software reset (refer to
Serial Interface section).
In parallel interface mode, the user has to tie RESET pin permanently high. (SCLK,
SDATA and SEN are used as parallel pin controls in this mode) The pin has an internal
100-k
pull-down resistor.
SCLK
This pin functions as serial interface clock input when RESET is low.
13
1
It functions as analog control pin when RESET is tied high and controls coarse gain
and internal/external reference selection. See
Table 4 for details.
The pin has an internal pull-down resistor to ground.
SDATA
This pin functions as serial interface data input when RESET is low. The pin has an
14
1
internal pull-down resistor to ground.
SEN
This pin functions as serial interface enable input when RESET is low.
15
1
It functions as analog control pin when RESET is tied high and controls the output
interface (LVDS/CMOS) and data format selection. See
Table 5 for details.
The pin has an internal pull-up resistor to AVDD.
CTRL1
These are digital logic input pins. Together they control various power down and
35
1
multiplexed mode. See
Table 6 for details.
