--IMPORTANT NOTE: The C80F1F2xx family does not support boundary scan.
--However, this family does support the boundary scan BYPASS and IDCODE
--instructions so that a single JTAG port may be used for system 
--testing.

--BSDL description for the Cygnal C8051F221 LQFP-32 package
--
--Some port names differ from the pinout to conform to
--BSDL syntax.  These varations are marked in the comments.
--
--The following pins have been defined as "LINKAGE" in order to 
--conform to BSDL standard:  
--XTAL2,VREF,
--VDD,GND
