6.3 MODES OF OPERATIONS
The ISD1740A/50A/60A devices are designed to operate in push-button operation only.
Push-button operation entails use of the REC , PLAY , FT , FWD , ERASE , VOL and
RESET pins to trigger operations. The internal state machine automatically configures the signal
path according to the operation requested. In this mode of operation, the internal state machine
takes full control of message management. This allows the user to record, playback, erase, and
forward messages without the needs to know the exact addresses of the messages storage inside
the memory. For additional information, please refer to Section 7.
