SPI

Low Power SPI 0 Reset Control.

Low Power SPI 0 Reset ControlControls reset state of the Low Power Serial Peripheral Interface 0 (LPSPI0). LPSPI0 provides SPI communication with power optimization features for efficient data exchange in low-power applications.

低功耗 SPI 0 重置控制，節能型串列外設介面

LPSPI0 Functions:

• Full-duplex serial communication up to several MHz
• Master and slave operation modes
• Configurable frame size (4-32 bits) and protocols
• Low-power operation with clock gating
• DMA and interrupt-driven data transfer support

註

Reset Effects:

• SPI interface returns to idle state
• Transmit and receive buffers are cleared
• Clock polarity and phase settings reset

• Chip select configurations return to defaults

  Flash Communication:

  // Setup LPSPI0 for external flash memory
  reset_ctrl.assert_reset(Control::LPSPI0);
  configure_spi_pins_and_clocking();
  reset_ctrl.release_reset(Control::LPSPI0);
  lpspi0_configure_master(8000000, SPI_MODE_0);
