The MSP430FR2311 i2c works in slave mode, We burned the same program to 50 chips, and only two of them I2C work abnormally. but the i2c work well when in active mode.When I2C master wite data to the slave, it was found through simulation that UCRXIFG0_1 was set but entered the USCI_I2C_UCSTPIFG interrupt, and then entered the USCI_I2C_UCRXIFG0 interrupt, that is, the order of entering the interrupt was reversed.The I2C frequence is about 180k. whe I adjust the frequence to 160k, the I2c work well. Is 180k too high for msp430fr2311 in LPM4 ?
