Detailed Errata Description
3. Clear the PVC interrupt request flag source SCU_DMPMITCLR.PVCMI2.
4. Clear the PVC interrupt request flag by writing to SCU_INTCLR.PVCMI2.
5. Clear the selected SCU request flag (default is SCU_1IC.IR).
RESET_X.H003 How to Trigger a PORST after an Internal Failure
There is no internal User Reset that restores the complete device including the power
system like a Power-On Reset. In some applications it is possible to connect ESR1 or
ESR2 with the PORST pin and set the used ESR pin as Reset output. With this a WDT
or Software Reset can trigger a Power-On Reset.
A detailed description is in the Application Note AP16103.
RTC_X.H003 Changing the RTC Configuration
The count input clock f_RTC for the Real Time Clock module (RTC) can be selected via bit
field RTCCLKSEL in register RTCCLKCON. Whenever the system clock is less than 4
times faster than the RTC count input clock (f_SYS < f_RTC × 4), Asynchronous Mode must
be selected (bit RTCCM = 1_B in register RTCCLKCON).
To assure data consistency in the count registers T14, RTCL, RTCH, the RTC module
must be temporarily switched off by setting bit MODEN = 0_B in register RTC_KSCCFG
before register RTCCLKCON is modified, i.e. whenever
• changing the operating mode (Synchronous/Asynchronous) Mode in bit RTCCM, or
• changing the RTC count source in bit field RTCCLKSEL.
In case power domain DMP_1 is switched off, it is not required to switch the RTC to
Asynchronous Mode, since it will receive a reset in any case.
StartUp_X.H002 FCONCS0..FCONCS4 Registers are Always Configured in
External Start-Up Mode
The Start-Up procedure in External Start Mode writes all the FCONCSx (x=0..4) registers,
independently on the number of CS-outputs selected.This has no effect for the user
because for unused CS lines the Start-Up procedure configures only the external bus
type into the registers but does not enable the output(s) for CS-functionality and they are
free available.
