Introduction
This program converts 1-byte HEX code into 2-byte BCD code. Set the HEX code in R1L. The BCD code is output to R0. In this program, the HEX code is doubled by decimal calculation sequentially beginning with the most significant bit and the results are added. This operation is repeated by a specified number of bits as the HEX code is converted into BCD code.
