I'm writing a spi driver for MPC8377E. I use a GPIO as the chip select signal.
I'm tring to use the NE or NF bits to decide when to read or when the transmit is over. 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. 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. Can anyone give me a help? Or anyone who has ever written the spi driver can give a source code for reference. Thank you! _________________________________________________________________ MSN新版在线社交网络，与您的MSN好友更全面互动！ http://im.live.cn/msn9/
