Set Burst Configuration Register command
The Set Burst Configuration Register command is used to write a new value to the Burst
Configuration Control Register which defines the burst length, type, X and Y latencies,
Synchronous/Asynchronous Read mode and the valid Clock edge configuration.
Two Bus Write cycles are required to issue the Set Burst Configuration Register command.
The first cycle writes the setup command and the address corresponding to the Set Burst
Configuration Register content. The second cycle writes the Burst Configuration Register
data and the confirm command. Once the command is issued the memory returns to Read
mode as if a Read Memory Array command had been issued.
The value for the Burst Configuration Register is always presented on A0-A15. M0 is on A0,
M1 on A1, etc.; the other address bits are ignored.
