Programming
The ISD2500 series is also ideal for playback-only applications, where single or multiple messages
are referenced through buttons, switches, or a microcontroller. Once the desired message
configuration is created, duplicates can easily be generated via a gang programmer.
7.2. OPERATIONAL MODES
The ISD2500 series is designed with several built-in Operational Modes that provide maximum
functionality with minimum external components. These modes are described in details as below. The
Operational Modes are accessed via the address pins and mapped beyond the normal message
address range. When the two Most Significant Bits (MSB), A8 and A9, are HIGH, the remaining
address signals are interpreted as mode bits and not as address bits. Therefore, Operational Modes
and direct addressing are not compatible and cannot be used simultaneously.
There are two important considerations for using Operational Modes. First, all operations begin initially
at address 0 of its memory. Later operations can begin at other address locations, depending on the
Operational Mode(s) chosen. In addition, the address pointer is reset to 0 when the device is changed
from record to playback, playback to record (except M6 mode), or when a Power-Down cycle is
executed.
Second, Operational Modes are executed when CE goes LOW. This Operational Mode remains in
effect until the next LOW-going CE signal, at which point the current mode(s) are sampled and
executed.
