Load/Latch and Control Functions – The Load/Latch function regulates the loading of the FX375 tone
frequency (D0 – D5, 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.

Latched
Data at the device inputs acts directly.
In this position data and/or functions are latched in.
'0 – 1 – 0' is a strobe pulse as shown in figures 3 and 4 (Timing).
