1 _{The address bits are decided by the mode serial flash is working. For 32-bit extended address the bits used are A26 - A0,}
and for default 24-bit address mode the bits used are A23 - A0.
2 _{Denotes that ‘size’- times one byte is transferred on the serial flash data bus. Total number of bytes must be provided in}
the TX Buffer or can be read from the RX Buffer.
The QSPI_MCR[ICO] field is mapped to the different command options belonging to the complete SFM
Command which is then sent to the serial flash. This is shown in detail in the following tables. Table 35-53
shows the commands usable in all flash access modes, Table 35-54 the commands specific to the
Individual Flash Modes, and Table 35-55 the commands specific to the Parallel Flash Mode. All size
