See if the name ands with number, truncate name to remove number and return number value.
| name | constant name, possibly ending with a number (decimal) if constant includes "__" (double "_") and has 4 decimals after __WWBB, those decimals are treated as bit field specs (WW 1..31 - width, BB - 0..31 - start bit ), i.e. "__0816" is the 3-rd byte of 4 in the 32-bit parameter These bit-filed modifiers are stored in bits 16..20 (bit) and 21..25 (width) of parameter address (number) |
