Note: On DA6x DSP, McASP has 16 serial data pins, n = 15.
On C6000 DSP, McASP has 8 serial data pins, n = 7.
† Check the device datasheet to see if AXEVTO/AREVTO and AXEVTE/AREVTE are supported. These signals are optional.
‡ AMUTEIN is not a dedicated McASP pin, but typically comes from one of the DSP's External Interrupt Pins.
