(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages referenced to V
SS
.The JTAG fuse-blow voltage, V
FB
, is allowed to exceed the absolute maximum rating. The voltage is
applied to the TDI/TCLK pin when blowing the JTAG fuse.

(1) It is recommended to power AV
CC
and DV
CC
from the same source. A maximum difference of 0.3 V between AV
CC
and DV
CC
can be
tolerated during power up and operation.
(2) The minimum operating supply voltage is defined according to the trip point where POR is going active by decreasing the supply
voltage. POR is going inactive when the supply voltage is raised above the minimum supply voltage plus the hysteresis of the SVS
circuitry.
(3) In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.
