ASN1C can parse any type of ASN.1 value specification, but it will only generate code for following value specifications:
BOOLEAN
INTEGER
REAL
ENUMERATED
Binary String
Hexadecimal String
Character String
OBJECT IDENTIFER
All value types except INTEGER and REAL cause an "extern" statement to be generated in the header file and a global value assignment to be added to the C or C++ source file. INTEGER and REAL value specifications cause #define statements to be generated.
