Version 2.0
The resonator and the load capacitors have to be placed as close as possible to the oscillator pins in order to minimize
output distortion and startup stabilization time. The loading capacitance values must be adjusted according to the
selected oscillator.
The EHS crystal is switched on and off using the EHSEN bit in
Analog Block Control register (SYS0_ANBCTRL)
3.2.3.3
External Low-speed (ELS) Clock
The low-speed oscillator can use 32768 crystal oscillator circuit.
3.2.3.4
CRYSTAL
Crystal devices are driven by LXIN, LXOUT pins. The 32768 crystal and 10pF capacitor must be as near as possible to
MCU. The ELS crystal is switched on and off using the ELSEN bit in
Analog Block Control register (SYS0_ANBCTRL)
Note: Connect the Crystal/Ceramic and C as near as possible to the LXIN/LXOUT/VSS pins of MCU. The
capacitor between LXIN/LXOUT and VSS must be 10pF.

Description
External clock source
(Bypass)
In Bypass mode, the external clock signal
(square, sinus or triangle) with ~50% duty
cycle must be provided to drive the XTALIN/
LXTALIN
pin
while
the
XTALOUT/
LXTALOUT pin should be the inverse of
the
input clock signal.
EHS X’tal can have a frequency of up to 25
MHz. Select this mode by setting EHSEN bit
in
