BITFIELD DESCRIPTION

[3..0] GPDAT[11..8] GPDAT[11..8] Data

If GPIO[11..8] is configured for INPUT:

0 = GPDAT[11..8] indicates that the signal GPIO[11..8] is at a ‘low’ level

1 = GPDAT[11..8] indicates that the signal GPIO[11..8] is at a ‘high’ level

If GPIO[7..0] is configured for OUTPUT:

0 = GPDAT[11..8] indicates that the signal GPIO[11..8] is being driven ‘low’

1 = GPDAT[11..8] indicates that the signal GPIO[11..8] is being driven ‘high’
