3.3.12. Read Buffer Control Register

The RdBufControl Register is read and write. On a read it returns the status of the corresponding read buffer control flags. On a write it changes the status of the corresponding read buffer control flags. Figure 3.8 shows the register bit assignments.

Table 3.13 lists the register bit assignments.

BitName Function
[31:28]RdBlockSizeSets size of block in 32bit words, 2RdBlockSize 1 to 64K words.
[27:16]-Reserved, read undefined, write as zero.
[15:8]RdFifoTideLevelSets tide level for read FIFO, depends on depth of FIFO.
[7:4]-Reserved, read undefined, write as zero.
[3]RdBlockFullMaskRead DPRAM block full flag mask to RdBufEvent bit.
[2]RdFifoTideMaskRead FIFO over tide level flag mask to RdBufEvent bit.
[1]RdFifoFullMaskRead FIFO full flag mask to RdBufEvent bit.
[0]RdFifoEmptyMaskRead FIFO empty flag mask to RdBufEvent bit.
