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 4-32 and described in Device TRM, Control Module Chapter.

Table 5-77 through Table 5-84 explain all cases with Virtual Mode Details for McASP1/2/3/4/5/6/7/8 (see Figure 5-59 through Figure 5-66).
