I am using an MSP430 USCI in SPI mode. I would like to confirm my understanding of this:
If UCTXIE and UCRXIE are explicitly disabled when the interface is initialized after UCSWRST is cleared the UCTXIFG and UCRXIFG should still operate as expected even though the interrupts are disabled, right?
From SLAU208M 188.8.131.52
The UCTXIFG interrupt flag is set by the transmitter to indicate that UCxTXBUF is ready to accept another character. An interrupt request is generated if UCTXIE and GIE are also set.
