Description
Serial Flash Address, register content is used as address for all following IP Commands.
30.4.3.12 Instruction Code Register (QSPI_ICR)
The Instruction Code Register consists of the generic instruction code (IC) and an additional parameter
section (ICO). This contains additional options to parameterize the command as shown in Table 30-53.
If the IC field is written successfully - while the module is in Serial Flash Mode and not busy - a new
command to the external serial flash device is started with that instruction code if this code is supported
by the module (see Section 30.7.1, Supported Instruction Codes in Winbond Devices).
The QSPI_ICR register is writeable only in SFM Mode.
Refer to Section 30.5.3.1, Issuing SFM Commands, for further details about the triggering of IP
Commands.
