Figure 3: Manual Reset Timing Diagram

Designers can use MCU to reset the module through NRST pin by setting NRST=Low for more

than 100us and then setting it to high for more than 5ms to fulfill the RESET.

2. SPI Interface

Figure 4: SPI Interface Timing Diagram

// SPI interface procedure

uint8_t SpiInOut( uint8_t outData )

{

/* Send SPIy data */

SPI_I2S_SendData( SPI_INTERFACE, outData );

while( SPI_I2S_GetFlagStatus( SPI_INTERFACE, SPI_I2S_FLAG_RXNE ) == RESET );

return SPI_I2S_ReceiveData( SPI_INTERFACE );
