3.3.18. Write Buffer Control Register

The WrBufControl Register is read and write. On a read it returns the status of the corresponding write buffer control flags. On a write it changes the status of the corresponding write buffer control flags. Figure 3.10 shows the register bit assignments.

Table 3.19 lists the register bit assignments.

BitName Function
[31:28]WrBlockSizeSets size of block in 32bit words, 2RdBlockSize 1 to 64K words.
[27:16]-Reserved, read undefined, write as zero.
[15:8]WrFifoTideLevelSets tide level for read FIFO, depends on depth of FIFO.
[7:4]-Reserved, read undefined, write as zero.
[3]WrBlockFullMaskWrite DPRAM block full flag mask to WrBufEvent bit.
[2]WrFifoTideMaskWrite FIFO over tide level flag mask to WrBufEvent bit.
[1]WrFifoFullMaskWrite FIFO full flag mask to WrBufEvent bit.
[0]WrFifoEmptyMaskWrite FIFO empty flag mask to WrBufEvent bit.
