Note 1: When the display digit is defined as N, N equals [decimal values to
which D3, D2, D1 and D0 are converted + 1]. In case of (D3, D2, D1,
D0)=(1, 0, 0, 0), N is 9. The first character code received after execut-
ing this command is despoiled to the 9th digit.

Note 2: The digit to which the cursor to make display ON or OFF belongs is
designated. When digit is defined as N, N equals [decimal values to
which D3, D2, D1 and D0 are converted + 1]. In case of (D3, D2, D1,
D0)=(1, 0, 0, 0), N is 9. ON/OFF control of the cursor which belongs
to the 9th digit is possible.
