4. SPI disable does not work in SLAVE mode
5. SPI data transfer hangs with CSR0.CSAAT==1 and MR.MODFDIS==0
6. Disabling SPI has no effect on flag TDRE flag
1. If the BOD level is higher than VDDCORE, the part is constantly resetted
2. When the main clock is RCSYS, TIMER_CLOCK5 is equal to PBA clock
3. VDDCORE power supply input needs to be 1.95V
4. Clock sources will not be stopped in STATIC sleep mode if the difference between
SPI disable does not work in SLAVE mode.
Fix/Workaround
Read the last received data, then perform a Software Reset.
When CSR0.CSAAT==1 and mode fault detection is enabled (MR.MODFDIS==0), the SPI
module will not start a data transfer.
Fix/Workaround
Disable mode fault detection by writing a one to MR.MODFDIS.
Disabling SPI has no effect on TDRE whereas the write data command is filtered when SPI
is disabled. This means that as soon as the SPI is disabled it becomes impossible to reset
the TDRE flag by writing in the TDR. So if the SPI is disabled during a PDCA transfer, the
PDCA will continue to write data in the TDR (as TDRE stays high) until its buffer is empty,
and all data written after the disable command is lost.
Fix/Workaround
Disable the PDCA, insert 2 NOPs, disable SPI. To continue the transfer: Enable SPI, enable
PDCA.
If the BOD level is set to a value higher than VDDCORE and enabled by fuses, the part will
be in constant reset.
Fix/Workaround
Apply an external voltage on VDDCORE that is higher than the BOD level and is lower than
VDDCORE max and disable the BOD.
When the main clock is generated from RCSYS, TIMER_CLOCK5 is equal to PBA Clock
and not PBA Clock / 128.
Fix/Workaround
None.
When used in dual power supply, VDDCORE needs to be 1.95V.
Fix/Workaround
When used in single power supply, VDDCORE needs to be connected to VDDOUT, which is
configured on revision C at 1.95V (typ.).
CPU and PBx division factor is too high
If the division factor between the CPU/HSB and PBx frequencies is more than 4 when going
to a sleep mode where the system RC oscillator is turned off, then high speed clock sources
will not be turned off. This will result in a significantly higher power consumption during the
sleep mode.
Fix/Workaround
Before going to sleep modes where the system RC oscillator is stopped, make sure that the
factor between the CPU/HSB and PBx frequencies is less than or equal to 4.
