Hello,
we have a question concerning the USART interrupt handling using the MSP430F1481 device:
When the USART0 interrupt is triggered the recieved character should switch to the corresponding function handling the rest of the data transfer.
In order to not jump to the start of the interrupt routine again when the next byte is recieved, the interrupt for RX is disabled in the Interrupt Enable Register (IE1) until the data transfer is completed.
But according to the family users guide disableing the URXIE0 also disables URXIFG0, which flags the incoming of a new, complete char.
Is this true, or is it still possible to poll the Interrupt Flag Register 1 for incoming bytes in U0RXBUF when the recieve interrupt has been disabled?
Kind regards,
Fabion et Fronk
