MX633 - PRELIMINARY INFORMATION
4.3.3 Control Logic
This block categorizes the nature of the signal into various decode output states and controls the two output pins.
See Table 3.
4.3.4 Xtal/Clock Oscillator
If the on-chip Xtal oscillator is to be used, then external components X1, R1, C1 and C2 are required. If an external clock
source is to be used, then it should be connected to the XTAL/CLOCK input pin and the XTAL pin should be left
unconnected.
