FSI Memory Cycle (LPC-SPI Command Transfer)
The FSI supports instructions other than Byte/Page-Program instructions, AAI-Program
instruction, Read instruction, and Fast-Read instruction by using an LPC-SPI command transfer.

FSI Command Space
Specific host address space can be used as FSI command space according to the CMDHBAR
settings. Figure 21.11 shows an example of FSI command space settings.

Figure 21.11 FSI Command Space Settings (Example)
As shown in figure 21.11, a host address ranging from H'EFFF_F000 to H'EFFF_F00F is used as
the FSI command space while the CMDHBAR register is set to H'EFFF.
