6.4 Burst access operation
6.4.2 Burst write access
When writing word-size data aligned on the 32-bit boundary, the M32000D3FP carries out a burst-transfer
_____________
by outputting the BURST signal. When burst-writing 32-bit data, the MSB-side 16-bit write bus cycle is
driven first, followed by the LSB-side 16-bit write bus cycle.
_____________
The BURST signal is synchronized with the CLKIN falling edge of the first bus access cycle, and "L" level
is output. It returns to "H" level in synchronization with the CLKIN falling edge of the last bus access cycle.
Addresses A8 to A30 are output for each cycle.

Note: "Hi-z" means high-impedance, and
indicates sampling timing.
Wait cycles can be inserted even when burst transferring by setting DC = "H".
Keep DC signal at the "H" level during idle cycles.
