AUTONSS=DISABLED, CTSEN=DISABLED, TFRCNT=AUTO, OPMD=NORMAL, ABORT=DISABLED, TXONREQ=DISABLED, FLOWMD=DISABLED
Mode Configuration
| OPMD | Operation Mode. 0 (NORMAL): Normal mode 1 (RECEIVE): Receive only mode. See the “Metron32 modifications” section for details 2 (TRANSMIT): Transmit only – none of the incoming data is stored in the RX FIFO. See the “Metron32 modifications” section for details 3 (FLOWCONTROL): Flow control mode - See the “Metron32 modifications” section for details |
| AUTONSS | Auto NSS Mode. 0 (DISABLED): See the “Metron32 modifications” section for details 1 (ENABLED): See the “Metron32 modifications” section for details |
| CTSEN | CTS Flow Control Enable. 0 (DISABLED): See the “Metron32 modifications” section for details 1 (ENABLED): See the “Metron32 modifications” section for details |
| FLOWMD | Flow Control Mode. 0 (DISABLED): See the “Metron32 modifications” section for details 1 (ENABLED): See the “Metron32 modifications” section for details |
| ABORT | Software Abort. 0 (DISABLED): No abort 1 (ENABLED): At the end of the current datum, abort, reset the SPIEN bit and reset this bit (SPI_SOFT_DIS). |
| TXONREQ | Transmit On Request. 0 (DISABLED): Data upon request mode is disabled 1 (ENABLED): Data upon request mode is enabled. See the “Metron32 modifications” section for details |
| NSSCNT | NSS Data Count. |
| NSSDELAY | NSS Delay. |
| TFRCNT | Transfer Count. 0 (AUTO): the apb_pbyte_en[3:0] signals determine the number of bytes to push/pop 1 (TRANSFER1): A single byte is written/read to/from the TX/RX Fifo. 2 (TRANSFER2): If apb_pbyte_en[3:0] equals 1 (less than apbw, which is 1), a single byte is written/read to/from the TX/RX Fifo. If apb_pbyte_en[3:0] > 1, two bytes are written/read to/from the TX/RX fifos. 3 (TRANSFER3): If apb_pbyte_en[3:0] > 2, three bytes are written/read to/from the TX/RX fifos.nIf apb_pbyte_en[3:0] = 2, two bytes are written/read to/from the TX/RX fifos.nIf apb_pbyte_en[3:0] = 1, a single byte is written/read to/from the TX/RX fifos. 4 (TRANSFER4): If apb_pbyte_en[3:0] = 1, a single byte is written/read to/from the TX/RX fifos.nElse, If apb_pbyte_en[3:0] = 2, two bytes are written/read to/from the TX/RX fifos.nElse, If apb_pbyte_en[3:0] = 3, three bytes are written/read to/from the TX/RX fifos.nElse, four bytes are written/read to/from the TX/RX fifos. |
