The clock-edge option is specified using either the plus or the minus character, or
both characters in the case of a dual-edge clock. The dual-edge clock (+-) is not
available on minor model 0 of the Neuron 3150 Chip.

Functional Block Declarations
The following is Neuron C syntax for functional block declarations. The
functional block is based on a functional profile definition from a resource file.
functional-block-declaration :
fblock-main fblock-name-section fblock-property-list-declaration
fblock-main fblock-name-section
fblock-main :
fblock FPT-identifier { fblock-body }
fblock FPT-identifier { }
FPT-identifier :
variable-identifier
The body of the functional block declaration consists of a list of network variable
members that the functional block implements. At the end of the list, the
functional block declaration can optionally declare a director function.
fblock-body :
fblock-member-list fblock-director-declaratio n
fblock-member-list
fblock-director-declaration
fblock-member-list :
fblock-member-list fblock-member ;
fblock-member ;
fblock-member :
net-var-identifier member-implementation
member-implementation :
