I completely read this wrong the first time... The common meaning of
#defines line this is

VEND1_GLOBAL_CFG_ is the register and what follows indicates some bits
in the register.

However, this is not true here, these are all registers. Maybe add
_REG to the end? It makes them different to other defines for
registers, but if i parsed it wrong, probably other will as well?

Revere Christmass tree. config_reg should be first.
