5.6 Read ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of 00h. Five read cycles
sequentially output the manufacturer code(ECh), and the device code and 3rd, 4th, 5th cycle ID respectively. The command register remains in Read ID
mode until further commands are issued to it. Figure 13 shows the operation sequence.
[Figure 13] Read ID Operation
5.7 Reset
The device offers a reset feature, executed by writing FFh to the command register. When the device is in Busy state during random read, program or
erase mode, the reset operation will abort these operations. The contents of memory cells being altered are no longer valid, as the data will be partially
programmed or erased. The command register is cleared to wait for the next command, and the Status Register is cleared to value C0h when WP is high.
If the device is already in reset state a new reset command will be accepted by the command register. The R/B pin changes to low for tRST after the
Reset command is written. Refer to Figure 14 below
