5.10.5.2. 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.
| 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 |
