TFR_CNT [23:0]: 24-bit Transfer Count
The TFR_CNT represents the required number of GDMA transfers. The maximum transfer count is
16M –1.
Channel 0/1 Current Source Register (GDMA_CSRC0, GDMA_CSRC1)
CURRENT_SRC_ADDR [31:0]: 32-bit Current Source Address
The CURRENT_SRC_ADDR indicates the source address where the GDMA transfer is just occurring.
During a block transfer, the GDMA determines the successive source addresses by adding to or
subtracting from the source base address. Depending on the settings you make to the control register,
the current source address will remain the same or will be incremented or decremented.
