// INFO ------------------------------------------------------------------------
|
||||
// Universal spi master
|
||||
//
|
||||
// * Supports all SPI bus modes
|
||||
// * Supports following SPI bus modes
|
||||
// mode 0 (CPOL = 0, CPHA = 0)
|
||||
// mode 1 (CPOL = 0, CPHA = 1)
|
||||
// mode 2 (CPOL = 1, CPHA = 0)
|
||||
// mode 3 (CPOL = 1, CPHA = 1)
|
||||
// * Moreover, universal spi master features separate parameters to set
|
||||
// clock edge to update data by spi master and
|
||||
// clock edge to latch data by spi master
|
||||
//
|
||||
// * Spi clock can be made free-running (some slaves require that)
|
||||
// * OE pin for bidirectional buffer connection, in case DO and DI pins are combined
|
||||
//
|
||||
// * Universal spi master successfully synthesize at clk speeds up to 200MHz
|
||||
// * That means, that SPI clocks up to 50MHz are supported
|
||||
// * Universal spi master successfully synthesize at clk speeds 200MHz and above
|
||||
// * That means, that SPI clocks up to 100MHz are supported
