Description
Externally selects active clock edge for clk_fgpo via fgpo_clk_pol
Note: This bit not used in the PNX17xx Series. All FGPO clock
control is in the clock module.
Enable output from buffer 2. This bit, along with bit 12 below, start
and stop FGPO DMA activity.
Enable output from buffer 1. This bit, along with bit 13 above, start
and stop FGPO DMA activity. If output from only one buffer is
desired, this bit must be used to start/stop DMA.
0 = record mode
1 = message mode
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
Encodes size of data samples output on fgpo_data:
00 = 8-bit data samples
01 = 16-bit data samples
10 = 32-bit data samples
11 = same as 10 above
0 = rising edge
1 = falling edge
