BDM mode returns the latched value of TPMxCNTH:L from the read buffer instead of the
frozen TPM counter value.
TPMxSC, TPMxCNTH or TPMxCNTL. Instead, in these conditions the TPM v2 does not clear
this read coherency mechanism.
TPMxCnVH:L register. In TPM v2, if only one byte of the TPMxCnVH:L registers was read
before the BDM mode became active, then any read of TPMxCnVH:L registers during BDM
mode returns the latched value of TPMxCNTH:L from the read buffer instead of the value in
the TPMxCnVH:L registers.
TPMxCnSC. Instead, in this condition the TPM v2 does not clear this read coherency
mechanism.
In this mode the TPM v3 does not allow the writes to TPMxCnVH:L registers. Instead, the
TPM v2 allows these writes.
In this mode and if (CLKSB:CLKSA not = 0:0), the TPM v3 updates the TPMxCnVH:L
registers with the value of their write buffer at the next change of the TPM counter (end of the
prescaler counting) after the second byte is written. Instead, the TPM v2 always updates these
registers when their second byte is written.
The following procedure can be used in the TPM v3 to verify if the TPMxCnVH:L registers
were updated with the new value that was written to these registers (value in their write buffer).
...
write the new value to TPMxCnVH:L;
read TPMxCnVH and TPMxCnVL registers;
while (the read value of TPMxCnVH:L is different from the new value written to
TPMxCnVH:L)
begin
end
...
In this point, the TPMxCnVH:L registers were updated, so the program can continue and, for
example, write to TPMxC0SC without cancelling the previous write to TPMxCnVH:L
registers.
In this mode and if (CLKSB:CLKSA not = 00), the TPM v3 updates the TPMxCnVH:L
registers with the value of their write buffer after that the both bytes were written and when the
read again TPMxCnVH and TPMxCnVL;
