· Values of the data codes (D0~D7)
The HT6221/HT6222 contain 32 and 64 ac-
tive keys, respectively. Each key corresponds
to a data code. For tape deck recording, the
HT6221/HT6222 provide three double-key
functions. The double-key, single-key, and
double-key operation rules are shown in Ta-
ble 3, Table 4, Timing 4, Timing 5 and Timing
6.
