SPI0_TXSEL
SPI0_RXSEL
PDMA SPI0 TX Selection
This filed defines which PDMA channel is connected to the on-chip peripheral SPI0 TX.
Software can configure the TX channel setting by SPI0_TXSEL. The channel
configuration is the same as SPI0_RXSEL field. Please refer to the explanation of
SPI0_RXSEL.
PDMA SPI0 RX Selection
This filed defines which PDMA channel is connected to the on-chip peripheral SPI0
RX. Software can change the channel RX setting by SPI0_RXSEL
4’b0000: CH0
4’b0001: CH1
4’b0010: CH2
4’b0011: CH3
4’b0100: CH4
4’b0101: CH5
4’b0110: CH6
4’b0111: CH7
4’b1000: CH8
Others : Reserved
Note: Ex : SPI0_RXSEL = 4’b0110, that means SPI0_RX is connected to PDMA_CH6
(Low Density should set as 4’b0000 for PDMA channel 0 only)
