REV.-A
(2) Data keys (other than the function keys)
Each data key issues the corresponding KEY code shown in Table 2-13 only once, when it is
pressed. When any key other than a function key depressed, its character code is repeatedly
generated by the sub-CPU provided that a feature called Auto Repeat is enabled. This feature
is enabled or disabled and the frequency of repetition is selected by software.
