Preliminary
4.13: GPDMA Array Write Address
This register is used to write the GPDMA internal array. The internal array is used to hold data for the DMA.
The array is organized as 64 32-bit words. The GPDMA Array Write Address is written with the address of the
word that is to be written. The GPDMA Array Data Register is written to write the addressed word. The
GPDMA Array Write Address is incremented each time the GPDMA Array Data Register is written, causing
repeated writes of the GPDMA Array Data Register to write sequential words in the array.
