7.2.1. Operational Modes Description
The Operational Modes can be used in conjunction with a microcontroller, or they can be hardwired to
provide the desired system operation.
M0 – Message Cueing
Message Cueing allows the user to skip through messages, without knowing the actual physical
addresses of each message. Each CE LOW pulse causes the internal address pointer to skip to the
next message. This mode is used for playback only, and is typically used with the M4 Operational
Mode.
M1 – Delete EOM Markers
The M1 Operational Mode allows sequentially recorded messages to be combined into a single
message with only one EOM marker set at the end of the final message. When this Operational
Mode is configured, messages recorded sequentially are played back as one continuous message.
M2 – Unused
When Operational Modes are selected, the M2 pin should be LOW.
M3 – Message Looping
The M3 Operational Mode allows for the automatic, continuously repeated playback of the message
located at the beginning of the address space. A message can completely fill the ISD2500 device and
will loop from beginning to end without OVF going LOW.
M4 – Consecutive Addressing
During normal operation, the address pointer will reset when a message is played through an EOM
marker. The M4 Operational Mode inhibits the address pointer reset on EOM , allowing messages to
be played back consecutively.
M5 -
CE -Level Activated
The default mode for ISD2500 devices is for CE to be edge-activated on playback and level-
activated on record. The M5 Operational Mode causes the CE pin to be interpreted as level-
activated as opposed to edge-activated during playback. This is especially useful for terminating
playback operations using the CE signal. In this mode, CE LOW begins a playback cycle, at the
beginning of the device memory. The playback cycle continues as long as CE is held LOW. When
CE
goes HIGH, playback will immediately end. A new CE LOW will restart the message from the
beginning unless M4 is also HIGH.
