Figure 65. nCS when CKMODE = 1 with an abort (T = CLK period)
When not in dual-flash mode (DFM = 0), only FLASH 1 is accessed and thus the BK2_nCS
stays high. In dual-flash mode, BK2_nCS behaves exactly the same as BK1_nCS. Thus, if
there is a FLASH 2 and if the application always stays in dual-flash mode, then FLASH 2
may use BK1_nCS and the pin outputting BK2_nCS can be used for other functions.
17.5 QUADSPI interrupts
An interrupt can be produced on the following events:
• Timeout
• Status match
• FIFO threshold
• Transfer complete
• Transfer error
Separate interrupt enable bits are available for flexibility.
