A37/ PWR Protected_Write (Write-pulse buffered, can be turned off)
Output active LOW. This signal corresponds to the /WR-signal, but
can be disabled by a RESET of the M-DIS-function. For missing
supply voltage, this signal has battery voltage and can therefore be
used for external components with battery buffering.
A61 /RESIN RESET-Input
Input active LOW. A connection with GND for about .5 sec. triggers a
RESET-pulse. Permanent connection causes a cyclic RESET-pulse
series of 1.6 sec duration. This input is not appropriate to stop the
controller for the duration of the activation of /RESIN.
A34 /RES RESET-Input/Output
Input/Output active LOW. This bi-directional connection might be
connected to GND. For the duration of this connection the controller
remains in the status of a continued RESET. The actuation of the /RES
should be bounce free. The slope of rising edge depends on the load
capacity.
A33 RES RESET-pulse output
Output active HIGH. This signal provides the inverse RESET-pulse of
/RES.
Attention:
An external RESET by wiring of A35 (/RES) doesn’t generate a signal
at A33. Only the RESET-pulses triggered by A61 will be present.
A13 BRESBattery-supplied RESET-signal
Output active HIGH. This signal is the inverse of /RES.
