Notes

sm - sex dependence/mutability

See the Header page for a complete discussion of this byte.

l# - locus ID

The locus of attachment of the chemo-emitter object. This three-character Locus ID represents 'organ,' 'tissue,' and 'site.' See the LOA - Emitters (C1 or C2 ) for the complete listing.

ce - chemical emitted

The chemical emitted when the chemical emitter binds to a cell in the brain. See the ChemList (C1 or C2) for a listing of all the chemicals in Creatures.

tt - threshold

Ranges from 00 to FF. Whether the emitter is analog or digital determines how it is combined with the current signal level and the gain to calculate output - see the 'emitter type' below.

sr - sample rate

Ranges from 00 to FF.

gg - gain

Ranges from 00 to FF. Whether the emitter is analog or digital determines how it is combined with the current signal level and the threshold to calculate output - see the 'emitter type' below.

et - emitter type

There is a set of two radio buttons on the Emitter gene editor, indicating that the 'emitter type' will be either analog or digital.

Analog (o/p = (signal - threshold) * Gain)
Digital (o/p = Gain if signal > threshold)

In addition, there are two check boxes below the chemical information:

All the observed values can be explained with the last three bits of the byte (with analog as the default emitter type):

Bit # 7 6 5 4 3 2 1 0  00 - 0 0 0 0 0 0 0 0  01 - 0 0 0 0 0 0 0 1  02 - 0 0 0 0 0 0 1 0  03 - 0 0 0 0 0 0 1 1  04 - 0 0 0 0 0 1 0 0  06 - 0 0 0 0 0 1 1 0

Bit 0 - Clear Bit 1 - Digital Bit 2 - Invert

In summary:

   00 - Analog
   01 - Analog   Clear
   02 - Digital
   03 - Digital  Clear
   04 - Analog          Invert
   06 - Digital         Invert
