Implementations
Bit 0 - Set the bit to enable full duplex communication. 1: enable 0: disable. Can be configured in CONF state.
Bit 5 - In the slave mode, this bit can be used to change the polarity of tsck. 0: tsck = spi_ck_i. 1:tsck = !spi_ck_i.
Bit 6 - spi cs keep low when spi is in done phase. 1: enable 0: disable. Can be configured in CONF state.
Bit 7 - spi cs is enable when spi is in prepare phase. 1: enable 0: disable. Can be configured in CONF state.
Bit 8 - In the slave mode, this bit can be used to change the polarity of rsck. 0: rsck = !spi_ck_i. 1:rsck = spi_ck_i.
Bit 9 - the bit combined with spi_mosi_delay_mode bits to set mosi signal delay mode. Can be configured in CONF state.
Bit 12 - In the write operations read-data phase apply 2 signals. Can be configured in CONF state.
Bit 13 - In the write operations read-data phase apply 4 signals. Can be configured in CONF state.
Bit 15 - 1: Enable the DMA CONF phase of next seg-trans operation, which means seg-trans will continue. 0: The seg-trans will end after the current SPI seg-trans or this is not seg-trans mode. Can be configured in CONF state.
Bit 17 - Set the bit to enable 3-line half duplex communication mosi and miso signals share the same pin. 1: enable 0: disable. Can be configured in CONF state.
Bit 24 - read-data phase only access to high-part of the buffer spi_w8~spi_w15. 1: enable 0: disable. Can be configured in CONF state.
Bit 25 - write-data phase only access to high-part of the buffer spi_w8~spi_w15. 1: enable 0: disable. Can be configured in CONF state.
Bit 26 - spi clock is disable in dummy phase when the bit is enable. Can be configured in CONF state.
Bit 27 - This bit enable the write-data phase of an operation. Can be configured in CONF state.
Bit 28 - This bit enable the read-data phase of an operation. Can be configured in CONF state.
Bit 29 - This bit enable the dummy phase of an operation. Can be configured in CONF state.
Bit 30 - This bit enable the address phase of an operation. Can be configured in CONF state.
Bit 31 - This bit enable the command phase of an operation. Can be configured in CONF state.
