15.5.3.8
This section provides detailed descriptions of the registers used to configure the FIFO interface. All of the
registers are 32 bits wide. The ECNTRL[FIFM] bit is set to indicate that data transfers take place over this
interface. Please refer to
protocols available.
15.5.3.8.1
The FIFO Configuration Register configures and enables the 8-bit FIFO interface.

describes the definition for the FIFOCFG register.
FIFO Configuration Register (FIFOCFG)
Reserved
Minimum inter packet gap. This sets the minimum number of cycles inserted between back-to-back frames
transmitted over the FIFO interface. If CRC is appended to frames, 7 cycles (8-bit mode) of non-payload
data separates packets.
Enable reset of FIFO receive function.
0 Do not reset the FIFO receiver.
1 Reset the FIFO receiver for as long as this bit is set.
Enable reset of FIFO transmit function.
0 Do not reset the FIFO transmitter.
1 Reset the FIFO transmitter for as long as this bit is set.
Enable FIFO receive function.
0 Disable reception over the FIFO interface, ignoring data presented to the signals.
1 Enable normal reception over the FIFO interface.
Enable FIFO transmit function.
0 Disable transmission over the FIFO interface.
1 Enable normal transmission over the FIFO interface.
