Microcontroller – MSP430 I2C No ACK Send Over Bus

I'm trying to get an I2C communication with an MSP430 (MSP430G2231) working. This is the first time I'm using a MSP430 for I2C and not sure if I'm doing everything correctly.

I have a Slave connected to SDA/SCL line of the Microcontroller with the Address: 0xE0 (the last Bit of the address is the Write Bit which needs to be set to 0). When monitoring the I2C bus with a logic analyzer I don't get any response from the slave to the send address – attached a picture of the bus communication. Are there any obvious errors in my code? Thanks a lot!

#include <msp430g2231.h>
#include <stdio.h>
#include <stdint.h>

    
void main(void) {
    WDTCTL = WDTPW + WDTHOLD;                                                   //disable watchdog timer
    

    
    //I2C init
    USICTL0 |= USIPE7 + USIPE6 + USIMST + USIOE + USISWRST;                     
    USICTL1 = USII2C;                                                           
    USICKCTL = USIDIV_7 + USISSEL_2 + USICKPL;                                 

    USICNT |= USIIFGCC;                                                         
    USICTL0 &= ~USISWRST;                                                      
    USICTL1 &= ~USIIFG;                                                                   
    
    while(1)
    {

        USISRL = 0x00;                                                              
        USICTL0 |= USIGE + USIOE;                                                   
        USICTL0 &= ~USIGE;
        
        //Send Data
        USISRL = 0xE0;                                                         
        USICTL0 |= USIOE;                                                           
        USICNT = 0x08;
        while((USICTL1 & USIIFG) != 0x01);                                          
        
        //Read Ack Bit
        USICTL0 &= ~USIOE;       
        USICNT |= 0x01;          
        USICTL0 |= USIOE;        
        
        //Stop
        USICTL0 |= USIOE;
        USISRL = 0x00;                                                              
        USICNT = 1;
        while((USICTL1 & USIIFG) != 0x01);                                          
      
        USISRL = 0xFF;                                                             
        USICTL0 |= USIGE;
        USICTL0 &= ~(USIGE+USIOE);
        
        for(delay=0; delay<100; delay++);
    }
}

Update:

I have changed the section for the ACK Reading to the following code and getting now still no ACK from the slave (see attatched second image):

//Read Ack Bit
USICTL0 &= ~USIOE;       
USICNT = 0x01;
USICTL0 |= USIOE;          
while((USICTL1 & USIIFG) != 0x01);
ack_flag = USISRL;
