porting plut-and-trust library for TI Hercules - stuck at I2C phNxpEse_clearReadBuffer

SE050 always NACKs over the very first custom ported axI2CRead. Is there any technical reference manual to learn how to perform a successful read from the SE?

Calling function phNxpEse_clearReadBuffer which is a part up minimal example (provided as a part of the MW package) results in issuing the very first i2c transaction which ultimately calls the ported axI2CRead which I populated. However, using a logic analyzer, I could observe that the SE never ACKs upon. The following is what I always get on the bus.

start-condition + 0x48 (  7 bit SE address in MSB) + 1 (Read) + NACK.

My guess is that I need to put the device in a "reading mode" by issuing a write beforehand. How can I verify this?
