■ Displaying running status (
3_07
) and running status 2 (
3_23
)
To display the running status and running status 2 in 4-digit hexadecimal format, each state has been assigned to
bits 0 to 15 as listed in Table 3.4-4 and Table 3.4-5 respectively. Table 3.4-6 shows the relationship between each of
the status assignments and the LED monitor display.
Table 3.4-7 gives the conversion table from 4-bit binary to hexadecimal.
