NOTE

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

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

CAUTION

The I/O Timings provided in this section are valid only for some McASP usage modes when the corresponding Virtual I/O Timings or Manual I/O Timings are configured as described in the tables found in this section.

Virtual IO Timings Modes must be used to ensure some IO timings for McASP1. See Table 7-2Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 7-62Virtual Functions Mapping for McASP1 for a definition of the Virtual modes.

Table 7-62 presents the values for DELAYMODE bit field.

Virtual IO Timings Modes must be used to ensure some IO timings for McASP2. See Table 7-2Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 7-63Virtual Functions Mapping for McASP2 for a definition of the Virtual modes.

Table 7-63 presents the values for DELAYMODE bit field.
