Operational Information
The logical inputs (D
0
– D
5
) are used to programme the FX375 tone frequency (Rx/Tx) as shown in Table 2
(below). Loading of data is carried out in either serial or parallel formats.

Table 2 Tone Programming
Load/Latch and Control Functions –
The Load/Latch function regulates the loading of the FX375 tone
frequency (D
0
– D
5
, Table 2) in either the serial or parallel modes. The Control input enables the flexible use of the
Rx/Tx and Private Enable functions, its use is illustrated in Table 3.
