Extend Example 7-26 to convert 10 packed BCD numbers stored in an array to unpacked BCD numbers and display on Port C and Port D, respectively. WebDec 2, 2013 · Since the arrays are 8 bytes and they store up to 16 digits, it appears that "packed" means BCD (binary coded decimal). Another packing method could be used, but BCD makes the most sense in this case. – BitBank. Dec 2, 2013 at 23:55. I think it's not BCD. If it is a BCD, array size should have been 32 not 8.

WebBCD Represenations . Binary coded decimal numbers may be represented in a number of ways. The most obvious is packed BCD, where each decimal digit is represented by a 4 bit field, and the digits are packed consecutively into a computer word. This scheme allows 4 digits to be packed into a 16 bit word, or 8 digits into a 32 bit word, as shown below.
