Table 6.12 shows the pin states in an idle cycle.
Table 6.12 Pin States in Idle Cycle
Notes: 1. Remains low in DRAM space RAS down mode.
6.10
This LSI has a write data buffer function for the external data bus. Using the write data buffer
function enables external writes and DMA single address mode transfers to be executed in parallel
with internal accesses. The write data buffer function is made available by setting the WDBE bit
to 1 in BCR.
Figure 6.83 shows an example of the timing when the write data buffer function is used. When this
function is used, if an external write or DMA single address mode transfer continues for two states
or longer, and there is an internal access next, an external write only is executed in the first state,
but from the next state onward an internal access (on-chip memory or internal I/O register
read/write) is executed in parallel with the external write rather than waiting until it ends.
