(1) TI recommends powering AVCC and DVCC from the same source. A maximum difference of 0.3 V between AVCC and DVCC can be tolerated during power up and operation.

(2) During V_CC and V_IO power up, it is required that V_IO ≥ V_CC during the ramp up phase of V_IO. During V_CC and V_IO power down, it is required that V_IO ≥ V_CC during the ramp down phase of V_IO (see Figure 8-1).

(3) The minimum supply voltage is defined by the supervisor SVS levels when it is enabled. See the Section 8.28 threshold parameters for the exact values and further details.

(4) TI recommends a capacitor tolerance of ±20% or better.

(5) Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.

NOTE: The device supports continuous operation with V_CC= V_SS while V_IO is fully within its specification. During this time, the general-purpose I/Os that reside on the V_IO supply domain are configured as inputs and pulled down to V_SS through their internal pulldown resistors. RST/NMI is high impedance. BSLEN is configured as an input and is pulled down to V_SS through its internal pulldown resistor. When V_CCreaches above the BOR threshold, the general-purpose I/Os become high-impedance inputs (no pullup or pulldown enabled), RST/NMI becomes an input pulled up to V_IO through its internal pullup resistor, and BSLEN remains pulled down to V_SS through its internal pulldown resistor.

NOTE: Under certain condtions during the rising transition of V_CC, the general-purpose I/Os that reside on the V_IO supply domain may actively transition high momentarily before settling to high-impedance inputs. These voltage transitions are temporary (typically resolving to high impedance inputs when V_CC exceeds approximately 0.9 V) and are bounded by the V_IO supply.

NOTE:The device remains in reset based on the conditions of the RSTDVCC and RST pins and the voltage present on DVCC voltage supply. If RSTDVCC or RST is held at a logic low or if DVCC is below the SVSH_+ minimum threshold, the device remains in its reset condition; that is, these conditions form a logical OR with respect to device reset.
