All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<OpcodeParamField>

public enum OpcodeParamField
extends java.lang.Enum<OpcodeParamField>

This enum defines the parameter primitives that opcodes are built from. Don't think about mnemonics. This is purely binary opcode. For instance: DD36bbii the 'b' field is an immediate byte and the 'i' field is an index byte. 28tltm the 't' field is an address word pointing to code (text). The "tl" is the lsb and the "tm" is the msb. Parameter info: bytes number of opcode bytes taken by the parameter sub the lower-case letter representing the parameter signed true if the numeric value is signed (branch offsets, for instance) address true if the numeric value is an address and not a constant (a RAM address, for instance) pc-offset true if the numeric value is offset from the PC (branch offsets, for instance) io true if the numeric value is a port (IO) address

Method Detail

values

public static OpcodeParamField[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (OpcodeParamField c : OpcodeParamField.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OpcodeParamField valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getParamField

public static OpcodeParamField getParamField(char tag)

This static method returns the OpcodeParamField based on single-letter name.

Parameters:

tag - the single letter name

Returns:

the OpcodeParamField that maps to the given letter

getNumBytes

public int getNumBytes()

getSubChar

public char getSubChar()

isAddress

public boolean isAddress()

isPCOffset

public boolean isPCOffset()

isIO

public boolean isIO()

isSigned

public boolean isSigned()
