The Power-On-Reset (POR) circuit remains active until an adequate voltage threshold has been
reached. This threshold will be reached also if the coil voltage ramps up in terms of a few volts
per second. It means that the tag can be moved slowly towards the reader without performance
loss. This in turn triggers the default start-up delay sequence. During this configuration period of
about 192 field clocks, the ATA5567 is initialized with the configuration data stored in EEPROM
block 0. During initialization of the configuration block 0, for all ATA55670x variants the load
damping is active permanently (see
damping option) achieve a longer read range based on the lower activation field strength.
If the POR-delay bit is reset, no additional delay is observed after the configuration period. Tag
modulation in regular-read mode will be observed about 3 ms after entering the RF field. If the
POR delay bit is set, the ATA5567 remains in a permanent damping state until 8190 internal
field clocks have elapsed.
T
Any field gap occurring during this initialization phase will restart the complete sequence. After
this initialization time the ATA5567 enters regular-read mode and modulation starts automati-
cally using the parameters defined in the configuration register.
