Note 2:
The XP supports internal oscillator, external crystal, or ceramic
resonator, external R/C and external CMOS drive clock modes. R16,
R17, R19, R20, R21, C10, C11 and Y1 are used to support the clock mode
selected. The development board is shipped configured for internal
oscillator. When using internal oscilator, pins 2 and 3 could be used
as GPIO ports PA0 and PA1. Table 1 shows the recommended clock mode
configurations.
