8 - TCC fault filtering on inverted fault is not working. Errata reference:
12512
12512
Fix/Workaround:
Use only non-inverted faults.
9 - When waking up from the STANDBY power save mode, the
SYNCBUSY.CTRLB and SYNCBUSY.STATUS bits may be locked to 1. Errata
reference: 12227
SYNCBUSY.CTRLB and SYNCBUSY.STATUS bits may be locked to 1. Errata
reference: 12227
Fix/Workaround:
After waking up from STANDBY power save mode, perform a software reset of
the TCC if you are using the SYNCBUSY.CTRLB and SYNCBUSY.STATUS bits
the TCC if you are using the SYNCBUSY.CTRLB and SYNCBUSY.STATUS bits
10 - When the Peripheral Access Controller (PAC) protection is enabled,
writing to WAVE or WAVEB registers will not cause a hardware exception.
Errata reference: 11468
writing to WAVE or WAVEB registers will not cause a hardware exception.
Errata reference: 11468
Fix/Workaround:
None
11 - If the MCx flag in the INTFLAG register is set when enabling the DMA,
this will trigger an immediate DMA transfer and overwrite the current
buffered value in the TCC register. Errata reference: 12155
this will trigger an immediate DMA transfer and overwrite the current
buffered value in the TCC register. Errata reference: 12155
Fix/Workaround:
None
39.2 Revision B
39.2.1 Device
1 - The software reset SWRST does not properly propagate inside the I2S
module. As a consequence, the slave mode may not be reconfigured
correctly and may result in unexpected behavior of the SYNCBUSY register.
Errata reference: 12848
module. As a consequence, the slave mode may not be reconfigured
correctly and may result in unexpected behavior of the SYNCBUSY register.
Errata reference: 12848
Fix/workaround:
None.
2 - PA24 and PA25 cannot be used as input when configured as GPIO with
continuous sampling (cannot be read by PORT). Errata reference: 12005
continuous sampling (cannot be read by PORT). Errata reference: 12005
Fix/Workaround:
- Use PA24 and PA25 for peripherals or only as output pins.
- Or configure PA31 to PA24 for on-demand sampling (CTRL[31:24] all zeroes)
and access the IN register through the APB (not the IOBUS), to allow waiting for
on-demand sampling.
