4.8 Operating Conditions
The supply voltage tolerance includes the supply voltage ripple, i.e. the supply voltage plus
ripple must not exceed the upper limit / violate the lower limit.
4.8.1 Power Up
There is no set order for switches on the supply voltages. However, all must be activated
within a period of 100 ms.
4.8.2 Wiring of CTRL-STBY
To ensure that the outputs remain at high-impedance upon power up (see 00), make sure
that the inputs pins
CTRL_STBY0-2
arein the PCB layout are switched to '0' (GND) during
this time (for example, link to XRESET pin), i.e. that the CTRL_STBY function is active.
Please note that the CTRL_STBY pins control both 3.3 V and 1.8/3.3 V pads.
CTRL_STBY0-2 must
therefore be deactivated
with the corresponding supply voltage
of the controlled IO buffers e.g. operation of the XHIF interface with 1.8 V
deactivation
of CTRL_STBY1, 2 = 1.8 V).
The table below shows which ERTEC 200P IO signals (see 3.2) are controlled with the

input pins:
