Function

TXIFG is not reset when NACK is received in I2C mode

Description

When the USCI_B module is configured as an I2C master transmitter the TXIFG is not reset after a NACK is received if the master is configured to send a restart (UCTXSTT=1 & UCTXSTP=0).

Workaround

Reset TXIFG in software within the NACKIFG interrupt service routine
