Initial State
RdBuf
[31:0]
FIFO-Tx read buffer (32x32-bit)
0x0000_0000
* Note: Read access to
FTx_RdBuf
makes FIFO-Tx to read data from the FIFO memory regardless of the address
given. That is, any address between 0x0040 and 0x0080 will trigger the FIFO memory read. This feature lets the
programmer use burst read from FIFO-Tx.
