Public Methods
public RegisterDescriptionEntry addName (String name)
Add a name for this register.
Parameters
| name | a name, cannot be empty or null; it can be a primary name or an alternate name |
|---|
Returns
- this object (allows chained calls)
public int getBitend ()
public int getBitsize ()
Get the register size in bits.
public int getBitstart ()
public String getName ()
Get the primary name.
Returns
- non-null, non-empty
public List<String> getNames ()
Get all the names for the register. The first entry in the list is the primary name.
Returns
- a list containing at least one entry
public int getNumber ()

Returns
- -1 if unspecified
public long getPureId ()
public int getSize ()
Get the register size in bytes, rounded up (eg, if the register is 6-bit long, the returned byte size will be 1).
public RegisterDescriptionEntry grp (int grp, int idx)
Defines the group from which register belongs.
Returns
