Description
This pin should be left unconnected.
The serial port input pins. Data applied here sets up the internal
state of the device, e.g. split point, scramble/clear, etc.
See Figure 10.
The positive supply rail. This pin must be decoupled to VSS by a
capacitor mounted close to the device.

Table 2: Recommended External Components
Recommended External Components Notes:
1. C5 and C6 should be low inductance types which are mounted close to their respective device pins.
2. For best results, a crystal oscillator design should drive the clock inverter input with signal levels of at
least 40% of VDD, peak to peak. Tuning fork crystals generally cannot meet this requirement. To obtain
crystal oscillator design assistance, please consult you crystal manufacturer.
