(4) The output format is in ASCII coded hexadecimal, which is headed by "&H" and delimited by "," (Hex. 2C). (4) The output format is in ASCII coded hexadecimal, which is headed by "&H" and delimited by "," (Hex. 2C). (4) The output format is in ASCII coded hexadecimal, which is headed by "&H" and delimited by "," (Hex. 2C). (4) The output format is in ASCII coded hexadecimal, which is headed by "&H" and delimited by "," (Hex. 2C).
The output format: Value of hand check state and the internal register, general output The output format: Value of hand check state and the internal register, general output The output format: Value of hand check state and the internal register, general output The output format: Value of hand check state and the internal register, general output
The first column next to "& H" responds to the hand check input and the following 4 columns responds to the The first column next to "& H" responds to the hand check input and the following 4 columns responds to the The first column next to "& H" responds to the hand check input and the following 4 columns responds to the The first column next to "& H" responds to the hand check input and the following 4 columns responds to the
