I'm writing a spi driver for MPC8377E.<BR>
I use a GPIO as the chip select signal.<BR>
I'm tring to use the NE or NF bits to decide when to read or when the transmit is over.<BR>
But I found that I have just write the command,the NE is set.Also I found that the transmit is not over the GPIO has been pulled up.<BR>
<BR>
So I don't know what the real meaning of these two bits.Or it just indicates that the register can be write but not the operation has been over.<BR>
<BR>
Can anyone give me a help?<BR>
Or anyone who has ever written the spi driver can give a source code for reference.<BR>
<BR>
