The 16-Mbit PSRAM has a timing which is not supported at read operation. If your sys-
tem has multiple invalid address signal shorter than t
operation which showed in abnormal timing, it needs a normal read timing at least dur-
ing 48 µs which showed in Avoidable Timing(1) or toggle the CS1 to high (> t
time at least which showed in Avoidable Timing(2)
