Functional Description
determines how the FPGA generates addresses, as shown
Table
starting at 0 and increments the address on every falling
CCLK edge. Conversely, when M0 = 1, the FPGA gener-
ates addresses starting at 0xFF_FFFF (all ones) and decre-
ments the address on every falling CCLK edge.

During configuration, the value of the M0 mode pin
58. When M0 = 0, the FPGA generates addresses
