Virtual IO Timings Modes must be used to guaranteed some IO timings for McASP1. See Table 7-2 Modes Summary for a list of IO timings
requiring the use of Virtual IO Timings Modes. See Table 7-60 Virtual Functions Mapping for McASP1 for a definition of the Virtual modes.
Table 7-60 presents the values for DELAYMODE bitfield.
