New SdFat optimized for Mega and Teensy 3.0

Where you able to use the ChipSelect-feature too? I set all the PCS bits in PUSHR but it never touches the CS state. This is my actual code:

inline uint16_t RF12_T3::rf12_xfer(uint16_t data) {
//  digitalWriteFast(10, LOW);
  SPI0_PUSHR = (1<<26) | (B11111 << 16) | data;    // send data (clear transfer counter, select all CS)
  while (! SPI0_TCR) ; // loop until transfer is complete
//  digitalWriteFast(10, HIGH);
  return SPI0_POPR;
}

Configuration is like this:

  // enables and configures SPI module
  // 16MHz 16bit transfers on CTAR0
  SPI0_CTAR0 = 0xF8010000;

Sorry for being a bit off-topic...
