unsigned int _BFaccDescCAL::func

2 bit function opcode

unsigned int _BFaccDescCAL::gcfe

GCFE address

unsigned int _BFaccDescCAL::gcfeTarget

set if command is for GCFE

unsigned int _BFaccDescCAL::gcrc

GCRC address

unsigned int _BFaccDescCAL::parity

parity -- does not include fixed portion

unsigned int _BFaccDescCAL::reg

3 bit register -- for dataless interpreted as an opcode
