EGISTER RECALL
:
PINS
DP/FL
AND
KT/EARTH
The RECALL function results in a calibrated pulse which drives the electronic line current interrupter via pin DP/FL or
KT/EARTH. Flash or earth selection and various flash interruption times depend on the diode options: FES A and FES B
(diode GOS =
on;
see Fig.15).
Fig.15 Recall mode timing diagram.
t
kd
= key pressed time (depends on user).
t
holdover
= hold-over time.
t
idp
= interdigit pause time.
t
interflash
= interflash hold-over time (only for TEA1069A).
a. Recall using flash; t
rc
= recall time using flash.
b. Recall using earth; t
ea
= recall time using earth.

AND

TO

The sense columns inputs and scanning rows outputs are
directly connected to a single contact keyboard matrix.
A second key entry will be valid after having released the
first button and after having pressed the second button.
Simultaneously pressing 2 buttons will disable the first
entered key. A key entry becomes valid when the
debounce time t
d
has elapsed.
The column and row pins (except ROW5) are HIGH when
V
DD
is below power-on reset trip level and when RESET is
HIGH.
ROW5 is an open-drain input/output; this configuration is
used to avoid current flowing in the on-line or standby
state. A pull-up resistor should be connected to ROW5.
ROW5 is LOW when V
DD
is below power-on reset trip level
and when RESET is HIGH.
