I use SPI on TS-7400 and i found some problem on it.

I write data to SSPDR and then read SSPDR back.

It's some thig like this

write_to_SSPDR(0xXXXX);
rawdata[0] = read_SSPDR();

write_to_SSPDR(0xXXXX);
rawdata[1] = read_SSPDR();

write_to_SSPDR(0xXXXX);
rawdata[2] = read_SSPDR();

write_to_SSPDR(0xXXXX);
rawdata[3] = read_SSPDR();

write_to_SSPDR(0xXXXX);
rawdata[4] = read_SSPDR();

I use oscilloscope 2 channel to moniter CLK, SSPTX , SSPRX , data out from SPI 
device is correct on timing.
But when i printf data to show, It have a problem.
rawdata[0] is zero, 
rawdata[1] is data on timing of rawdata[0],
rawdata[2] is data on timing of rawdata[1],
...etc

Any suggest to help me?
Thank you .
