9-3. Read Identification (RDID)
The RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The Macro-
nix Manufacturer ID and Device ID are listed as "Table 6. ID Definitions".
The sequence of issuing RDID instruction is: CS# goes low→ sending RDID instruction code→24-bits ID data out
on SO→ to end RDID operation can drive CS# to high at any time during data out.
While Program/Erase operation is in progress, it will not decode the RDID instruction, therefore there's no effect on
the cycle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby
stage.
