Below is an example:
Given sampling rate set to 6.4 kHz, using the ISD1916 to record four messages: three messages of 2.5 seconds
and one message of 12.5 seconds, then the memory can be assigned as follows:
• Low active input:
• For 8kHz sampling frequency, if REC
• For 6.4kHz sampling frequency, if REC
• Recording begins from the start address to end address and LED
• Recording ceases whenever:
