Note:
It is possible to change the comparison values and the comparison configurations while the
channel 0 is enabled (see
To prevent unexpected comparison match, the user must use the

(CMPxVUPD and CMPxMUPD) to change respectively the comparison values and the compari-
son configurations while the channel 0 is still enabled. These registers hold the new values until

the values for the next period.
CAUTION: to be taken into account, the write of the CMPxVUPD register must be followed by a
write of the CMPxMUPD register.
Note:
Depending on the interrupt mask in the IMR1 and IMR2 registers, an interrupt can be generated
at the end of the corresponding channel period (CHIDx in the ISR1 register), after a fault event
(FCHIDx in the ISR1 register), after a comparison match (CMPMx in the ISR2 register), after a
comparison update (CMPUx in the ISR2 register) or according to the transfer mode of the syn-
chronous channels (WRDY and UNRE in the ISR2 register).
If the interrupt is generated by the CHIDx or FCHIDx bits, the interrupt remains active until a
read operation in the ISR1 register occurs.
If the interrupt is generated by the WRDY, UNRE, CMPMx or CMPUx bits, the interrupt remains
active until a read operation in the ISR2 register occurs.
A channel interrupt is enabled by setting the corresponding bit in the IER1 and IER2 registers. A
channel interrupt is disabled by setting the corresponding bit in the IDR1 and IDR2 registers.
”Sync Channels Update Period Register” on page 1008
If the SCUPUPD update register is written several times between two updates, only the last writ-
ten value is taken into account.
Changing the update period does make sense only if there is one or more synchronous channels
and if the update method 1 or 2 is selected (UPDM=1 or 2 in

If the update registers CMPxVUPD and CMPxMUPD are written several times between two
updates, only the last written value are taken into account.
