(1) Stresses beyond those listed under absolute maximum ratingsmay 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
conditionsis 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 TEST pin when blowing the JTAG fuse.
(3) Higher temperature may be applied during board soldering process according to the current JEDEC J-STD-020 specification with peak
reflow temperatures not higher than classified on the device label on the shipping boxes or reels.

(1) The CPU is clocked directly with MCLK. Both the high and low phase of MCLK must not exceed the pulse width of the specified
maximum frequency.
(2) Modules might have a different maximum input clock specification. See the specification of the respective module in this data sheet.
