NOTES
1Interrupt/Flag pins retain both functions concurrently. If IMASK is set to enable the corresponding interrupts, then the DSP will vector to the appropriate interrupt
vector address when the pin is asserted, either by external devices, or set as a programmable flag.
2SPORT configuration determined by the DSP System Control Register. Software configurable.
