Write in assembly language a character translation function 'int HEX2BIN(char h)' which uses only if- then ('IT') structures and no branching opcodes to decode the uppercase ASCII hex numerics, e.g. '0' = 0x30 => 0, '1' 0x31 => 1, ..., 'F'=0x46 => 15 and returns the int32_t of their binary value or -1 if the function argument is not a hex ASCII numeric. Demonstrate that your function works correctly for all 256 8-bit values (you'll want an automated test procedure).
