MCO: Maximum Carry On. The value of these bits sets the maximum carry on that the FLEX
decoder will follow. For example, if the FLEX decoder receives a carry on of 3 over the air and
MCO is set to 1, the FLEX decoder will only carry on for one frame. (value after reset=3)
12.3.7
The contents of this section apply to the FLEX™ Roaming Decoder. They are not applicable to
the FLEX™ Non-Roaming Decoder.
The timing control packet gives the host control of the timing used when the FLEX decoder is in
asynchronous mode. The packet ID for the timing control packet is 6.

AST: A-word Search Time. The value of these bits sets the A-word search time for all
asynchronous A-word searches in units of 80ms (e.g. value of 1 is 80ms, value of 2 is 160ms, etc.)
If the value is 0, the FLEX decoder defaults to the 1-minute (MOT=1) or 4-minute (MOT=0) A-
word search time controlled by the MOT bit in the configuration packet. (Value after reset=0)
ABT: Asynchronous Battery-save Time. The value of these bits sets the battery save time (time
from the beginning of one automatic noise detect to the beginning of the next automatic noise
detect) in asynchronous mode in units of 80ms (e.g. value of 1 is 80ms, value of 2 is 160ms, etc.)
If the value is 0, the battery save time is set to the default value of 1.5 seconds. The minimum
allowed ABT is 320ms, therefore values of 1, 2, 3, and 4 are invalid. (Value after reset=0)
