Pull-up and pull-down for JTAG and
Boot mode.
Used for HSE: the value depends on
the crystal characteristics.
A typical value is 390 Ω .
Used for LSE: the value depends on
the crystal characteristics.
This resistor value is given only as a
typical example.
For low pass filter
Ceramic capacitor
Used for LSE: the value depends on
the crystal characteristics. Fits for
MC-306 32.768K-E3, which has a
load capacitance of 6 pF.
Used for HSE: the value depends on
the crystal characteristics.
