Displaying running status
To display the running status in hexadecimal format, each state has been assigned to bit 0 to 15 as
listed in Table 3.7. Table 3.8 shows the relationship between each of the status assignments and the
LED monitor display. Table 3.9 gives the conversion table from 4-bit binary to hexadecimal.
