+// .cfast defines register preloading for the fast target sided flashing routines
+// .fast references the machine code to be used
+// each sequence can be composed out of one or more cycles.
+// There are five cycle types (operations) so far :
+// Write (w) Read (r) Compare (r) Toggle (t) Poll (p) .
+// Each cycle takes an ADR and a data word tupel: 'w0x0:0xf0'

+// for device offset and width
+// Data can be immediate (e.g. 0x) or actual data word %D,
+// both will be expanded to data bus width.
+// Read generates a warning only if results differ, while Compare will exit with 
+// failure status.
+// Toggle reads from address, ANDs the result with the given mask and waits
+// until the result stabilizes, as Poll waits for a zero result.
