I/O Pins
Fix/Workaround
Solution 1: Disable OSC0 by writing a zero to the Oscillator Enable bit in the System Control
Interface (SCIF) Oscillator Control Register (SCIF.OSC0CTRL.OSCEN) before going to a
sleep mode where OSC0 is disabled.
Solution 2: Pull down or up XIN0 and XOUT0 with 1MOhm resistor.
PB10 is not 3.3V tolerant.
PB10 should be grounded on the PCB and left unused.
Fix/Workaround
None.
Analog multiplexing consumes extra power
Current consumption on VDDIO increases when the voltage on analog inputs is close to
VDDIO/2.
Fix/Workaround
None.
PA02, PB01, PB04, PB05, and RESET_N have half of the pull-up strength
Pins PA02, PB01, PB04, PB05, and RESET_N have half of the specified pull-up strength.
Fix/Workaround
None.
JTAG is enabled at power up
The JTAG function on pins PA00, PA01, PA02, and PA03, are enabled after startup. Normal
I/O module functionality is not possible on these pins.
Fix/Workaround
Add a 10kOhm pullup on the reset line.
MCKO and MDO[3] are swapped in the AUX1 mapping
When using the OCD AUX1 mapping of trace signals MDO[3] is located on pin PB05 and
MCKO is located on PB01.
Fix/Workaround
Swap pins PB01 and PB05 if using OCD AUX1.
