5. Center-Aligned PWM
— Edge-Aligned PWM
— Center-Aligned PWM
— TPMxCnVH:L = TPMxMODH:L [SE110-TPM case 1]
— TPMxCnVH:L = (TPMxMODH:L - 1) [SE110-TPM case 2]
— TPMxCnVH:L is changed from 0x0000 to a non-zero value [SE110-TPM case 3 and 5]
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
TPM counter changes from (TPMxMODH:L - 1) to (TPMxMODH:L). If the TPM counter is
a free-running counter, then this update is made when the TPM counter changes from $FFFE
to $FFFF. Instead, the TPM v2 makes this update after that the both bytes were written and
when the TPM counter changes from TPMxMODH:L to $0000.
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
TPM counter changes from (TPMxMODH:L - 1) to (TPMxMODH:L). If the TPM counter is
a free-running counter, then this update is made when the TPM counter changes from $FFFE
to $FFFF. Instead, the TPM v2 makes this update after that the both bytes were written and
when the TPM counter changes from TPMxMODH:L to (TPMxMODH:L - 1).
In this case, the TPM v3 produces 100% duty cycle. Instead, the TPM v2 produces 0% duty
cycle.
In this case, the TPM v3 produces almost 100% duty cycle. Instead, the TPM v2 produces 0%
duty cycle.
