Methods

impl R

pub fn spi_clk_equ_sysclk(&self) -> SPI_CLK_EQU_SYSCLK_R

Bit 31 - In the master mode 1: spi_clk is eqaul to system 0: spi_clk is divided from system clock.

pub fn spi_clkdiv_pre(&self) -> SPI_CLKDIV_PRE_R

Bits 18:30 - In the master mode it is pre-divider of spi_clk.

pub fn spi_clkcnt_n(&self) -> SPI_CLKCNT_N_R

Bits 12:17 - In the master mode it is the divider of spi_clk. So spi_clk frequency is system/(spi_clkdiv_pre+1)/(spi_clkcnt_N+1)

pub fn spi_clkcnt_h(&self) -> SPI_CLKCNT_H_R

Bits 6:11 - In the master mode it must be floor((spi_clkcnt_N+1)/2-1). In the slave mode it must be 0.

pub fn spi_clkcnt_l(&self) -> SPI_CLKCNT_L_R

Bits 0:5 - In the master mode it must be equal to spi_clkcnt_N. In the slave mode it must be 0.
