NOTE

To configure the desired virtual mode the user must set MODESELECT bit and DELAYMODE bitfield for each corresponding pad control register.

The pad control registers are presented in Table 4-3 and described in Device TRM, Chapter 18 - Control Module.

Table 7-55 through Table 7-62 explain all cases with Virtual Mode Details for McASP1/2/3/4/5/6/7/8 (see Figure 7-43 through Figure 7-50).
