与MRF24J40MA进行SPI通信时丢失的位

大家好！我已经开发了一个应用与MRF24J40MA收发器的图像传输和设备的设置不正常工作。我发现，当我在一个寄存器中写入时，我总是丢失我发送的最后一个“1”。我知道这是因为下面的任务是读取相同的寄存器（延迟后）。如果我写一个孤立的‘1’（而不是一个‘1’的字符串），我只得到零。例子：Po& & Gt；0000 1000 GET，0000；0000 -----------------------------& 0000；1110GET & 0000；1100i在写了0x2C之后有一个读取结果的例子。不是软件错误。我已经检查过，我没有在寄存器中保留一个位，在所有的操作中都是CS＝‘0’。时钟线也以正确的方式工作。读/写的代码是：

    Hello everyone!
I've been developing an application for transmission of images with the MRF24J40MA transceiver and the set up of the of the device is not working properly. I've detected that I always lose the last '1' that I send when I  write in a register. I know this because the following task I do is read the same register (after a delay). If I write an isolated '1' (not a string of '1') , I only get zeros. Example:
Put-> 0000 1000
Get ->0000 0000
--------------------------------------
Put-> 0000 1110
Get ->0000 1100
I have an example of a read result after having written a 0x2c. As you can seein the image attached the first one can`t be detected but is "present", so that makes me think that is not a software bug.

I've already  checked that I'm not writing on a reserved bit in the register, and CS = '0' during all the operation.
The clock line is working in a proper way too.
The code to read/write is:
short int SPI1_Write(short int value,bool read) {//read indicates if It's a write/read access
   
    if(SPI1STATLbits.SPIROV != 0){//overflow bit

        short int TempVar;
        TempVar = SPI1BUFL; // Clears BF
        SPI1STATLbits.SPIROV =0;
    }
    short int dummy_value=0;
   
    while((SPI1STATLbits.SPITBF)){
        LCD_SendString("TX full!");//wait while TX buffer is full. Verify bit 1*/
    }
    SPI1BUFL=value;

    if(read==true){//if reading from spi slave

       SPI1STATLbits.SPIROV = 0;
       while(SPI1STATLbits.SPITBF); // wait for TX buffer to empty
        SPI1BUFL=0x00; // write to TX buffer (force CLK to run for RX transfer)

       while(SPI1STATLbits.SPIRBE){//WAIT while RX buffer not full
            LCD_SendString("RX empty!");
            
        }//wait while receive buffer not full

        dummy_value=SPI1BUFL;//SPI1BUFL;RB10;RF7;PORTFbits.RF5;
        
        if(SPI1STATLbits.FRMERR==1) while(1) LCD_SendString("error!");

        return dummy_value;
    }
    else {
        
        return 0;
    }
   

}
