-/** @file dk4ahd.h ASCIIHex decoder.
-
-First initialize the decoder using the dk4ahex_dec_init() function.
-
-Add text characters using the dk4ahex_dec_add() function.
-The function returns DK4_EDSTM_ACCEPT if the text character was successfully
-stored in the decoder without completing a byte.
-The DK4_EDSTM_FINISHED return code indicates that a byte was finished, use
-dk4ahex_output() to retrieve it.
-The DK4_EDSTM_STOP return code indicates that an end of data (EOD) marker
-was found.
-
-After feeding all text characters into the decoder use dk4ahex_finish()
-to check whether there is an unprocessed half-byte stored.
-If the function returns DK4_EDSTM_FINISHED, use dk4ahex_output() to
-retrieve the final byte.
-
-Note: The call to dk4ahex_finish() is also necessary after
-obtaining DK4_EDSTM_STOP from dk4ahex_dec_add().
