When powering down, VRC33 and VDDSYN have no delta requirement to each other, because the bypass
capacitors internal and external to the device are already charged. When not powering up or down, no delta
between VRC33 and VDDSYN is required for the VRC to operate within specification.
There are no power up/down sequencing requirements to prevent issues such as latch-up, excessive current
spikes, and so on. Therefore, the state of the I/O pins during power up and power down varies depending
on which supplies are powered.
Table 7 gives the pin state for the sequence cases for all pins with pad type pad_fc (fast type).
Table 8 gives the pin state for the sequence cases for all pins with pad type pad_mh (medium type) and
pad_sh (slow type).
The values in Table 7 and Table 8 do not include the effect of the weak-pull devices on the output pins
during power up.
Before exiting the internal POR state, the pins go to a high-impedance state until POR negates. When the
internal POR negates, the functional state of the signal during reset applies and the weak-pull devices
(up or down) are enabled as defined in the device reference manual. If VDD is too low to correctly
propagate the logic signals, the weak-pull devices can pull the signals to VDDE and VDDEH.
To avoid this condition, minimize the ramp time of the VDD supply to a time period less than the time
required to enable the external circuitry connected to the device outputs.
