4. Write the corresponding SIMR (mask register) bit with a 1 to allow interrupts to be generated to

the core.

5. The pin value can be read at any time using PDATC.

NOTE

After connecting CTS or CD to the SCC/FCC, the user must also choose the

normal operation mode in GSMR[DIAG] to enable and disable SCC/FCC

transmission and reception with these pins.

The IDMA-DREQ signals on port C can assert an external request to the CP instead of asserting an

interrupt to the core. Each line can be programmed to assert an interrupt request upon a high-to-low change

or any change as configured in SIEXR.

NOTE

Do not program the IDMAx-DREQ pins to assert external requests to the

IDMA, unless the IDMA is used. Otherwise, erratic operation occurs.
