20.3.2. FPGA Routing
Two sets of SPI Master and two sets of SPI Slave Pins are available for routing to the FPGA. The signal names are shown below. For more information on routing SPI signals to the FPGA, refer to the HPS Component Interfaces chapter.
Signal Name | Signal Width | Direction | Description |
---|---|---|---|
spim_mosi_o | 1 | Out | Transmit data line for the SPI master |
spim_miso_i | 1 | In | Receive data line for the SPI master |
spim_ss_in_n | 1 | In | Master Contention Input |
spim_mosi_oe | 1 | Out | Output enable for the SPI master |
spim_ss0_n_o | 1 | Out | Slave Select 0 Slave select signal from SPI master |
spim_ss1_n_o | 1 | Out | Slave Select 1 Allows second slave to be connected to this master |
spim_ss2_n_o | 1 | Out | Slave Select 2 Allows third slave to be connected to this master |
spim_ss3_n_o | 1 | Out | Slave Select 3 Allows fourth slave to be connected to this master |
spim_sclk_out | 1 | Out | Serial clock output |
Signal Name | Signal Width | Direction | Description |
---|---|---|---|
spis_miso_o | 1 | Out | Transmit data line for the SPI Slave |
spis_mosi_i | 1 | In | Receive data line for the SPI Slave |
spis_ss_in_n | 1 | Out | Master Contention Input |
spis_miso_oe | 1 | Out | Output enable for the SPI Slave |
spis_sclk_in | 1 | In | Serial clock input |
