TCA6424A: Register read back procedure

Part Number: TCA6424A

Hi Team,

I have two simple question about a read back procedure of TCA6424A on I2C bus.

1. Is it acceptable to use “STOP and START condition” instead of “Repeated START condition”?
2. Is it necessary to leave high on SDA by Master as NACK at the end byte of read?

My customer expect to use "STOP and START condition" and ACK also.
