Conditions for
t
SPO Timing Measurement
The time required for the transition from Power-On to Base mode is called
t
SPO. It is
measured under the following conditions:
Precondition: The pad supply is valid, i.e.
V
DDPB is above 3.0 V and remains above 3.0 V
even though the XC2785X is starting up. No debugger is attached.
Start condition: Power-on reset is removed (PORST = 1).
End condition: External pin toggle caused by first user instruction executed from FLASH
after startup.
Conditions for
t
SSO Timing Measurement
The time required for the transition from Stopover to Stopover Waked-Up mode is
called
t
SSO. It is measured under the following conditions:
Precondition: The Stopover mode has been entered using the procedure defined in the
Programmer’s Guide.
Start condition: Pin toggle on ESR pin triggering the startup sequence.
End condition: External pin toggle caused by first user instruction executed from PSRAM
after startup.

LV = selected SWD voltage level
6) The limit
V
LV - 0.10 V is valid for the OK1 level. The limit for the OK2 level is VLV - 0.15 V.
