5.1.1. Record (
REC
) Operation
Low active input, level-hold for level-trigger or falling edge for edge-trigger with debounce required.
For 8kHz sampling frequency, if
REC
is held at Low for a period equal to 1 sec or more, then level
recording is activated. However, if
REC
is pulsed Low for less than 1 sec, then edge-trigger recording
is initiated.
For 6.4kHz sampling frequency, if
REC
is held at Low for a period equal to 1.25 sec or more, then
level recording is activated. However, if
REC
is pulsed Low for less than 1.25 sec, then edge-trigger
recording is initiated.
Recording begins from the start address to end address and
LED
is on.
Recording ceases whenever
REC
returns to High in level-hold mode or a subsequent lower going
pulse appears while in edge-trigger mode or when end address is reached. Then an EOM marker is
written at the end of message. And
LED
is off.
Then the device will automatically power down.
This pin has an internal pull-up device.
Once
REC
is active, input on
