SPRS269A – FEBRUARY 2005 – REVISED APRIL 2005

By default, the McASP0, VP1, VP2, and I2C peripherals are disabled on power up. In order to use these

peripherals on the DM643 device, the peripheral must first be enabled in the Peripheral Configuration

during run-time. Care should also be taken to ensure that no accesses are being performed before

disabling the peripherals. To help minimize power consumption in the DM643 device, unused

peripherals may be disabled.

Figure 3-3 shows the flow needed to enable (or disable) a given peripheral on the DM643 device.
