Processor and Architecture
1. Increased Power Consumption in VDDIO in sleep modes
2. In 3.3V Single Supply Mode the Analog Comparator inputs affects the device’s ability
1. PA17 has low ESD tolerance
Not sampled.
1. Privilege violation when using interrupts in application mode with protected system
2. Hardware breakpoints may corrupt MAC results
None
If the OSC0 is enabled in crystal mode when entering a sleep mode where the OSC0 is dis-
abled, this will lead to an increased power consumption in VDDIO.
Fix/Workaround
Solution 1: Disable the 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 any sleep mode where the OSC0 is disabled
Solution 2: Pull down or up XIN0 and XOUT0 with 1MOhm resistor.
to start
When using the 3.3V Single Supply Mode the state of the Analog Comparator input pins can
affect the device’s ability to release POR reset.
This is due to an interaction between the Analog Comparator input pins and the POR cir-
cuitry. The issue is not present in the 1.8V Single Supply Mode or the 3.3V Supply mode
with 1.8V Regulated I/O Lines.
Fix/Workaround
ACREFN (pin PA16) must be connected to GND until the POR reset is released and the
Analog Comparator inputs should not be driven higher than 1.0 V until the POR reset is
released.
PA17 only tolerates 500V ESD pulses (Human Body Model).
Fix/Workaround
Care must be taken during manufacturing and PCB design.
stack
If the system stack is protected by the MPU and an interrupt occurs in application mode, an
MPU DTLB exception will occur.
Fix/Workaround
Make a DTLB Protection (Write) exception handler which permits the interrupt request to be
handled in privileged mode.
Hardware breakpoints on MAC instructions may corrupt the destination register of the MAC
instruction.
Fix/Workaround
Place breakpoints on earlier or later instructions.
