NOTE
The EMIF_nWAIT signal has a pull-up on it. The EMIF module generates a "Wait Rise"
interrupt whenever it detects a rising edge on the EMIF_nWAIT signal. This interrupt
condition is indicated as soon as the device is powered up. This can be ignored if the
EMIF_nWAIT signal is not used in the application. If the EMIF_nWAIT signal is actually used
in the application, then the external slave memory must always drive the EMIF_nWAIT signal
such that an interrupt is not caused due to the default pull-up on this signal.
NOTE
The lower-order interrupt channels are higher priority channels than the higher-order interrupt
channels.
NOTE
The application can change the mapping of interrupt sources to the interrupt channels via the
interrupt channel control registers (CHANCTRLx) inside the VIM module.
