REGDEF
I
Pullup
Invalid Register Read Select
This active low input controls the default values that are read from invalid
register locations.
If REGDEF = ‘1’ All invalid register locations will return a value of ‘0000’
when read.
If REGDEF = ‘0’ All invalid register locations will return a value of ‘ffff’ when
read.
