the Nonvolatile Configuration Register, the device would respond with an ACK after the device
address byte and Pointer Register byte but then respond with a NACK instead of an ACK after
the Master has sent the upper byte of configuration register data. When attempting to read a
register during a nonvolatile busy operation, the device will NACK instead of ACK after the
AT30TS750’s device address byte has been received.

Other Commands
The AT30TS750 incorporates additional commands for other device functions. The command
opcode consists of a single byte of data that is sent from the Master to the AT30TS750 in place of
the Pointer Register byte. Therefore, the device must first be addressed by the Master and then
given the subsequent command opcode.
Sending any of the command opcodes to the
AT30TS750 will not change the contents of the Pointer Register byte.
