DA14531 I2C READ NACK

Hello,

I have interfaced an i2C sensor SHT40 with the DA14531MOD.

I am using it in the 7bit addressing mode. 

I am trying to read the register address 0x89.

slave address (SHT40) is 0x44.

for which I am getting an ACK from the slave for I2C_WRITE command. but a NACK when I read the slave after transmitting 0x89.
