Read Burst Interrupt Opeation
Read burst interrupt functions is only allowed on a burst of 8. Interrupting a burst of 4 is prohibited. Read burst of 8
can only be interrupted by another Read command. Read burst interruption by Write command or Precharge command
is prohibited. Read burst interrupt must occur exactly two clocks after previous Read command. Any other Read burst
interrupt timings are prohibited. Read burst interruption is allowed to any bank inside DRAM. Read burst with Auto
Precharge enabled is not allowed to be interrupted. Read burst interruption is allowed by a Read with Auto Precharge
command. All command timings are referenced to burst length set in the mode register. They are not referenced to
actual burst. For example, Minimum Read to Precharge timing is AL+BL/2 where BL is the burst length set in the mode
register and not the actual burst(which is shorter beacuse of interrupt).
