But in the program under the registers we are using the AE which is related to write address. Isnt it?

you are trying to create a problem that does not exist there is no such thing as write address or read address in pbp there is only the address
a pbp i2c address is the 7bit manufacturer's address left shifted 1 bit, the only variation is for crappy ancient eeproms where the "page"
address forms part of the address[control] , but bit0 is still under pbp control regardless

you don't quibble the hserout command adding start and stop bits to your serial transmission or even calculating the parity and inserting it also



why should the i2c "high level" commands not be able to set the r/w bit as required, after all that's why you use pbp. it stops you needing to dig into the bowels of i2c transactions

the manual



lets not hear any more of this nonsense
