Device Handle
This function allocates a parameter RAM table from PRAM. You use
PRAM tables for linking transfers together. You can either specify a
table number or specify –1 and the function will pick an unused one for
you. The return value is a device handle and may be used for APIs that
require a device handle. If the table could not be allocated, then
EDMA_HINV is returned.
If you finish with the table and wish to free it up again, call
EDMA_FreeTable().
EDMA_HANDLE hEdmaTable;
...
hEdmaTabel = EDMA_AllocTable(–1);

EDMA_CHA_CNT
Compile time constant that holds the number of EDMA channels.
