+// this define is for compatibility of LPC15xx or LPC8xx SPI
+// if not defined, the fastWrite() sets the EOT flag after transmission. Then the MOSI line is set high (or high Imp?) 
+// This is not the same behaviour as with older SPI hardware. 
+// For use in standard SPI this may be ok, for use as NRZ driver as in wsLib (driver for WS2812 LED) the EOT must not be set.
