CVS: jtag/hardware_access HIL.c,1.11,1.12

Update of /cvsroot/mspgcc/jtag/hardware_access
In directory sc8-pr-cvs7.sourceforge.net:/tmp/cvs-serv26811/jtag/hardware_access

Modified Files:
	HIL.c 
Log Message:
- F20xx support (spy-bi-wire capable devices, use 4 wire JTAG mode)
- separate segment A lock handling (F2xx) so that the flash funclet + data fits again in 128 bytes
- debug messages and internal cleanups
- more updates for MSP430X arch

 Parameters:
  state: The device TST pin is set to state (0/1).
+        Special values: if one of the bits in the mask 0xff00 is set, then
+        is the extra delay disabled, allowinf for very quick changes on the
+        TST pin (default is to make a delay in the millisecond range)
+        
+        Examples:
+            HIL_TST(1) ->  test on vcc, 10 ms delay before and after pin change
+            HIL_TST(0) ->  test on gnd, 10 ms delay before and after pin change
+
+            HIL_TST(0xff01) ->  test on vcc, as fast as possible
+            HIL_TST(0xff00) ->  test on gnd, as fast as possible
