4.6.4 Software Reset
The SPI interface of the AT25512 can be reset by toggling the CS input. If the CS line is already in the Active state, it must complete a transition from the Inactive state (≥VIH) to the Active state (≤VIL) and then back to the Inactive state (≥VIH) without sending clocks on the SCK line. Upon completion of this sequence, the device will be ready to receive a new opcode on the SI line.
