Fix/Workaround
PCNT_E102
PCNT Pulse Width Filtering does
not work
The PCNT Pulse Width Filter does not work as intended.
Do not use the pulse width filter, i.e. ensure FILT = 0 in
PCNTn_CTRL.
USB_E111
Using EM2 with system running on
USHFRCO
Entering EM2 when both the system clock (HFCLK) and the
USB core clock (USBCCLK) are running on USHFRCO will
result in a lock-up.
Use either HFRCO or HFXO for the system clock (HFCLK)
if EM2 is employed in USB applications. Alternatively, the
EMVREG bit in EMU_CTRL can be set. This allows EM2 to
be used at the cost of extra current consumption in EM2.
In rare cases with high data throughput, a transmission can
fail when this mode is enabled.
Use the GATED mode of LEMOSCCTRL for the best energy
efficiency. The NONE mode can be used to disable energy
savings.
Running the system on USHFRCO
will not work with EM2 in USB applications.
USB_E112
SUSPEND in LEMOSCCTRL
Do not use the SUSPEND mode of
LEMOSCCTRL in USB_CTRL.
