OCTOSPI control register
| EN | Enable 0 (B_0x0): OCTOSPI disabled 1 (B_0x1): OCTOSPI enabled |
| ABORT | Abort request 0 (B_0x0): No abort requested 1 (B_0x1): Abort requested |
| DMAEN | DMA enable 0 (B_0x0): DMA disabled for indirect mode 1 (B_0x1): DMA enabled for indirect mode |
| TCEN | Timeout counter enable 0 (B_0x0): The timeout counter is disabled, and thus the chip-select (NCS) remains active indefinitely after an access in memory-mapped mode. 1 (B_0x1): The timeout counter is enabled, and thus the chip-select is released in the memory-mapped mode after TIMEOUT[15:0] cycles of external device inactivity. |
| DMM | Dual-memory configuration 0 (B_0x0): Dual-memory configuration disabled 1 (B_0x1): Dual-memory configuration enabled |
| MSEL | External memory select 0 (B_0x0): External memory 1 selected (data exchanged over IO[3:0]) 1 (B_0x1): External memory 2 selected (data exchanged over IO[7:4]) |
| FTHRES | FIFO threshold level 0 (B_0x0): FTF is set if there are one or more free bytes available to be written to in the FIFO in indirect-write mode, or if there are one or more valid bytes can be read from the FIFO in indirect-read mode. 1 (B_0x1): FTF is set if there are two or more free bytes available to be written to in the FIFO inindirect-write mode, or if there are two or more valid bytes can be read from the FIFO inindirect-read mode. 31 (B_0x1F): FTF is set if there are 32 free bytes available to be written to in the FIFO in indirect-write mode, or if there are 32 valid bytes can be read from the FIFO in indirect-read mode. |
| TEIE | Transfer error interrupt enable 0 (B_0x0): Interrupt disabled 1 (B_0x1): Interrupt enabled |
| TCIE | Transfer complete interrupt enable 0 (B_0x0): Interrupt disabled 1 (B_0x1): Interrupt enabled |
| FTIE | FIFO threshold interrupt enable 0 (B_0x0): Interrupt disabled 1 (B_0x1): Interrupt enabled |
| SMIE | Status-match interrupt enable 0 (B_0x0): Interrupt disabled 1 (B_0x1): Interrupt enabled |
| TOIE | Timeout interrupt enable 0 (B_0x0): Interrupt disabled 1 (B_0x1): Interrupt enabled |
| APMS | Automatic status-polling mode stop 0 (B_0x0): Automatic status-polling mode is stopped only by abort or by disabling the OCTOSPI. 1 (B_0x1): Automatic status-polling mode stops as soon as there is a match. |
| PMM | Polling match mode 0 (B_0x0): AND-match mode, SMF is set if all the unmasked bits received from the device match the corresponding bits in the match register. 1 (B_0x1): OR-match mode, SMF is set if any of the unmasked bits received from the device matches its corresponding bit in the match register. |
| FMODE | Functional mode 0 (B_0x0): Indirect-write mode 1 (B_0x1): Indirect-read mode 2 (B_0x2): Automatic status-polling mode (relevant in regular-command protocol only) 3 (B_0x3): Memory-mapped mode |
