Data Buffer Write Cycle Ready Timing
When the data buffer is in write mode and the last available
space for a data word has been filled, the data buffer ready
signal will go inactive (MPBRDY = LOW) two clock cycles
following the last clock cycle that the write enable is active
(MPWE = LOW). Any attempt to write data to a “full” data
buffer (MPWE = LOW while MPBRDY = LOW) does not
result in a successful write to the buffer. Valid and invalid
data buffer writes are shown in Figure 14.
