XSPIM control register
| MUXEN | Multiplexed mode enable 0 (B_0x0): No multiplexing, hence no arbitration 1 (B_0x1): XSPI1 and XSPI2 are multiplexed over the same bus. |
| MODE | XSPI multiplexing mode 0 (B_0x0): if MUXEN = 0 direct mode, if MUXEN = 1 arbitration mode to output Port 1 1 (B_0x1): if MUXEN = 0 swapped mode, if MUXEN = 1 arbitration mode to output Port 2 |
| CSSEL_OVR_EN | Chip select selector override enable 0 (B_0x0): CSSEL_OVR_O1 and CSSEL_OVR_O2 bit values are ignored, the chip select signals from OCTOSPIs or XSPIs are transmitted unconditionally 1 (B_0x1): CSSEL_OVR_O1 and CSSEL_OVR_O2 bit values are taken into account |
| CSSEL_OVR_O1 | Chip select selector override setting for XSPI1 0 (B_0x0): XSPI1 can only use NCS1 (accesses using NCS2 are ignored) 1 (B_0x1): XSPI1 can only use NCS2 (accesses using NCS1 are ignored) |
| CSSEL_OVR_O2 | Chip select selector override setting for XSPI2 0 (B_0x0): XSPI2 can only use NCS1 (accesses using NCS2 are ignored) 1 (B_0x1): XSPI2 can only use NCS2 (accesses using NCS1 are ignored) |
| REQ2ACK_TIME | REQ to ACK time |
