12-BIT AUTORELOAD TIMER (Cont’d)
Figure 36. PWM Signal Example
Output Compare Mode
To use this function, the OE bit must be 0, other-
wise the compare is done with the shadow register
instead of the DCRx register. Software must then
write a 12-bit value in the DCR0H and DCR0L reg-
isters. This value will be loaded immediately (with-
out waiting for an OVF event).
The DCR0H must be written first, the output com-
pare function starts only when the DCR0L value is
written.
When the 12-bit upcounter (CNTR) reaches the
value stored in the DCR0H and DCR0L registers,
the CMPF0 bit in the PWM0CSR register is set
and an interrupt request is generated if the CMPIE
bit is set.
Note: The output compare function is only availa-
ble for DCRx values other than 0 (reset value).
Caution: At each OVF event, the DCRx value is
written in a shadow register, even if the DCR0L
value has not yet been written (in this case, the
shadow register will contain the new DCR0H value
and the old DCR0L value), then:
– If OE=1 (PWM mode): the compare is done be-
– if OE=0 (OCMP mode): the compare is done be-
tween the timer counter and the shadow register
(and not DCRx)
tween the timer counter and DCRx. There is no
PWM signal.

The compare between DCRx or the shadow regis-
ter and the timer counter is locked until DCR0L is
written.
11.2.4 Low Power Modes
11.2.5 Interrupts
Notes:
1. The interrupt events are connected to separate
interrupt vectors (see Interrupts chapter).
They generate an interrupt if the enable bit is set in
the ATCSR register and the interrupt mask in the
CC register is reset (RIM instruction).
