To perform a Multiple Byte Write operation, follow the same procedure as for a Single Byte Write until the first data byte is written. After writing the first byte, instead of generating a Stop Condition, the microcontroller should continue writing data bytes. To conclude the write operation, after sending the last data byte, the microcontroller should generate a Stop Condition. **Invalid Memory Addressing** The valid memory range of the IS3750 goes from addresses 0 to 3599 (0x0E0F). If a Multiple Byte Write Operation is performed with a Pointer Register within the valid memory range (0 to 3599) but exceeds the last memory register (3599), a rollover to register 0 will occur. If a Multiple Byte Write Operation is performed with a Pointer Register outside from the valid memory range (greater than 3599), the IS3750 will respond with a NACK upon receiving the first data byte.
