PRODUCTION DATA.
Depending on the device variant (see Section 3), the device with USS module supports a high-frequency crystal on the USSXT pins. External bypass capacitors for the crystal oscillator pins are required. Serially connect a 22-Ω resistor close to the USSXTOUT pin (see Figure 7-4). The USSXT does not support bypass mode, so it is not possible to apply digital clock signals to the USSXTIN pin. Never connect the USSXTIN pin to a power supply line (AVCC, DVCC, or PVCC). If the USSXT pins are not used, terminate them according to Section 4.6.
Figure 7-4 shows a typical connection diagram.
Consider the following items for the USSXT layout:
Figure 7-5 shows the recommended PCB layout.
