MODE_IND

Mode Indicator. This line indicates module

activity. It can source enough current to drive

a small LED, causing it to flash. The duration

of the flashes indicates the module’s current

state.

RESET2

This line resets the module when pulled low.

It should be pulled high for normal operation.

CMD_DATA_IN

Command Data In. Input line for the serial

interface commands. If serial control is not

used, this line should be tied to supply to

minimize current consumption.

POWER_DOWN

Power Down. Pulling this line low places the

module into a low-power state. The module

is not functional in this state. Pull high for

normal operation. Do not leave floating.

LATCH_EN

If this line is high, then the status line outputs

are latched (a received command to activate

a status line toggles the output state). If low,

then the output lines are momentary (active

for as long as a valid signal is received).
