Hi! I have CC430F6147 board. I'm setup MSCM1 = 0xEF, i hope state machine be in TX state, but they go to TX_UNDERFLOW. I transmit packet every 0,007sec.
How i can stay in TX state whitout switch to IDLE or RX or FSTXON state?

Have you taken a look at these http://www.ti.com/litv/zip/slac525a and http://www.ti.com/lit/an/slaa465c/slaa465c.pdf?

To stay in TX MCSM1.TX_OFFMODE=10. If you get TX_UNDERFLOW you have to check the number of byte you try to send vs how many bytes you have in the FIFO.
