Write with Auto Precharge
During a write cycle, the auto precharge starts at the timing that is equal to the value of tDPL(min.) after the last data word
input to the device.
In summary, the auto precharge cycle begins relative to a reference clock that indicates the last data word is valid. In the
table below, minus means clocks before the reference; plus means clocks after the reference.
