Virtual IO Timings Modes must be used to guaranteed some IO timings for McASP3/4/5/6/7/8. See Table 7-2 Modes Summary for a list of IO
timings requiring the use of Virtual IO Timings Modes. See Table 7-62 Virtual Functions Mapping for McASP3/4/5/6/7/8 for a definition of the
Virtual modes.
Table 7-62 presents the values for DELAYMODE bitfield.
