EAE:
End of Addresses Enable. When this bit is set, the EA bit in the Status Packet will be set
immediately after the S5T8701 decodes the last address word in the frame if there was any
address detected in the frame. When this bit is cleared, the EA bit will never be set.
ON:
Turn On Decoder. Set if the S5T8701 should be decoding FLEX signals. Clear if signal processing
should be off (very low power mode). If the
ON
bit is changed twice and the control packets making
the changes are received within 2ms of each other, the S5T8701 may ignore the double change
and stay in its original state (e.g. if it is turned off then on again within 2ms it may stay on and
ignore the off pulse). Therefore it is recommended that the host insures a minimum of 2ms between
changes in the
ON
bit. (value after reset=0)
NOTES:
Turning off the S5T8701 must be done using the following sequence. This sequence is performed automatically by
the FLEX stack software version 1.2 and greater.
1. Turn off the S5T8701 by sending a Control Packet with the
ON
bit cleared.
2. Turn on the S5T8701 by sending a Control Packet with the
ON
bit set.
3. Turn off the S5T8701 by sending a Control Packet with the
ON
bit cleared.
Timing between these steps is specified below and is measured from the positive edge of the last clock of one
packet to the positive edge of the last clock of the next packet:
The minimum time between steps 1 and 2 is 2ms or the programmed shut down time, whichever is greater.
The programmed shut down time is the sum of all the of the times . programmed in the used Receiver Shut
Down Settings Packets.
There is no maximum time between steps 1 and 2.
The minimum time between steps 2 and 3 is 2ms.
The maximum time between steps 2 and 3 is the programmed warm up time minus 2ms. The programmed
warm up time is the sum of all the of the times programmed in the used Receiver Warm Up Settings
Packets.
