Description
・Precautions when turning on and off VDDI pin and VDDE pin was added as indicated by the shading
below.
・Precautions when turning on and off VDDI pin and VDDE pin
To ensure the reliability of LSI devices, do not continuously apply only VDDE pin for about a minute
when VDDI is off.
When VDDE pin is changed from off to on, the power noise may make it impossible to retain the
internal state of the circuit.
Power-on : Supply voltage of VDDI pin → analog → Supply voltage of VDDE pin → signal
Power-off : Signal → Supply voltage of VDDE pin → analog → Supply voltage of VDDI pin
There is no problem for turning on and off the power (VDDI/VDDE/analog) simultaneously.
