MSP430F4132 I2C Problem

Other Parts Discussed in Thread: MSP430F4132

Hello,

I am using the MSP430F4132.  I have it configured as an I2C slave device.  I have very simple code set up to do a one byte read and a one byte wright based off of the Rx and Tx interrupts.   The master can wright to it with no problems.  When the master executes a read, about 50% of the time a bit is missing from the data.  For example,  when the MSP430 slave should be transmitting 0x88, it transmits 0x80. 

I have looked at the signals with a scope and verified that a bit is left out of the data transmission.  It is not a problem with the master device code.

Does anybody have any ideas ?

Thanks
