None.
UP, WGPB, EGPB, SSB, PGPFB, EAGPF commands).
After a flash fuse write operation (FLASHC LP, UP, WGPB, EGPB, SSB, PGPFB, EAGPF
commands), the following flash read access may return corrupted data. This erratum does
not affect write operations to regular flash memory.
Fix/Workaround
The flash fuse write operation (FLASHC LP, UP, WGPB, EGPB, SSB, PGPFB, EAGPF
commands) must be issued from internal RAM. After the write operation, perform a dummy
flash page write operation (FLASHC WP). Content and location of this page is not important
and filling the write buffer with all one (FFh) will leave the current flash content unchanged. It
is then safe to read and fetch code from the flash.
RTC peripheral bus clock (PBA) is divided by a factor of four or more relative to the
HSB clock
Writes to control (CTRL), top (TOP) and value (VAL) in the RTC are discarded if the RTC
peripheral bus clock (PBA) is divided by a factor of four or more relative to the HSB clock.
Fix/Workaround
Do not write to the RTC registers using the peripheral bus clock (PBA) divided by a factor of
four or more relative to the HSB clock.
The RTC CLKEN bit (bit number 16) of CTRL register is not available.
Fix/Workaround
Do not use the CLKEN bit of the RTC on Rev B.
Consider the following assembly code sequence:
A
B
If a hardware breakpoint is placed on instruction B, and instruction A is a memory access
instruction, register file updates from instruction A can be discarded.
Fix/Workaround
Do not place hardware breakpoints, use software breakpoints instead. Alternatively, place a
hardware breakpoint on the instruction before the memory access instruction and then sin-
gle step over the memory access instruction.
