Processor and Architecture

Power Manager
1. Privilege violation when using interrupts in application mode with protected system
2. Hardware breakpoints may corrupt MAC results
1. Flash selfprogramming may fail in one wait state mode
1. Clock sources will not be stopped in Static mode if the difference between CPU and
2. External reset in Shutdown mode
3. Disabling POR33 may generate spurious resets
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.
Writes in flash and user pages may fail if executing code located in the address space
mapped to the flash and if the flash controller is configured in one wait state mode (the Flash
Wait State bit in the Flash Control Register (FCR.FWS) is 1).
Fix/Workaround
Solution 1: Configure the flash controller in zero wait state mode (FCR.FWS=0).
Solution 2: Configure the HMATRIX master 1 (CPU Instruction) to use the unlimited burst
length transfer mode (MCFG1.ULBT=0) and the HMATRIX slave 0 (FLASHCDW) to use the
maximum slot cycle limit (SCFG0.SLOT_CYCLE=255).
PBx division factor is larger than 4
If the division factor between the CPU/HSB and PBx frequencies is more than 4 when enter-
ing a sleep mode where the system RC oscillator (RCSYS) is turned off, the high speed
clock sources will not be turned off. This will result in a significantly higher power consump-
tion during the sleep mode.
Fix/Workaround
Before going to sleep modes where RCSYS is stopped, make sure the division factor
between the CPU/HSB and PBx frequencies is less than or equal to 4.
If an external reset is asserted while the chip is in Shutdown mode, the Power Manager will
register this as a Power-on Reset (POR), and not as a SLEEP reset, in the Reset Cause
register (RCAUSE).
Fix/Workaround
None.
Depending on operating conditions, POR33 may generate a spurious reset in one of the fol-
lowing cases:
- When POR33 is disabled from the user interface.
- When SM33 supply monitor is enabled.
