FSK SPI mode uses the uWIRE interface, Figure 1 in the datasheet shown the timing diagram. SPI programming is 24-bit long. Up Hi Noel Thank You, but what format of transfer 24 bitsfor FSK-SPI? Is it Figure 19 with sequence of bits: RW=0, ADDR_REG34=010_0010...
在芯片资料上极性和相位一般表示为CPOL(ClockPOLarity)和CPHA(ClockPHAse),极性和相位组合成4种工作模式。CPOLCPHAMODE0 0 0 MODE1 0 1 MODE2 1 0 MODE3 1 1CPOL:SPI空闲时的时钟信号电平(1:高电平, 0:低电平)CPHA:SPI在时钟第几个边沿采样(1:第二个边沿开始, 0:第一个边沿开始 ...
2、主机从从机读数据 这种情况下,主机先发送 8 bits,第一位为 1 代表这次是读,然后 AD6 ~ AD0 是想要读的寄存器地址,然后 SDO 开始返回数据。 4、SPI timing diagram Tcsb_setup:建立时间 Tcsb_hold:保持时间 tsckl:低电平时间 tsckh:高电平时间 SCK period :Tsckl + tsckh 一般情况下 Tsckl = tsckh...

SPI的CPOL,表示当SCLK空闲idle的时候,其电平的值是低电平0还是高电平1: CPOL=0,时钟空闲idle时候的电平是低电平,所以当SCLK有效的时候,就是高电平,就是所谓的active-high; CPOL=1,时钟空闲idle时候的电平是高电平,所以当SCLK有效的时候,就是低电平,就是所谓的active-low; ...

Timing Diagram of SPI Modes Note: 1. SCLK provides interface timing for SPI NAND. Address, data and commands are latched on the rising edge of SCLK. Data is placed on SO at the falling edge of SCLK. 2. When CS# is 0, the device is placed in active mode. When CS# goes 1, the ...
