Description
Internal voltage regulator output of 1.8 V. If enabled,
this output should be connected to the V_DD1.8 (and
V_DDW if wide-range IO is at 1.8 V) supplies of the
chip. If the regulator is disabled, then this pin should
be treated as another V_DD1.8 supply input to the chip
Factory test mode. This pin should be grounded or
left floating (has an internal pull-down) for normal
operation. Pull-down is always enabled
Additional address pin for debug use. Should be
grounded or left floating (has an internal pull down)
for normal use. Pull-down is always enabled
This pin must be grounded for normal operation
Reserved
No connection. This pin should be left floating
