ADuC841/ADuC842/ADuC843
PULSE-WIDTH MODULATOR (PWM)
The PWM on the ADuC841/ADuC842/ADuC843 is a highly
flexible PWM offering programmable resolution and an input
clock, and can be configured for any one of six different modes
of operation. Two of these modes allow the PWM to be config-
ured as a ∑- DAC with up to 16 bits of resolution. A block
diagram of the PWM is shown in Figure 47. Note the PWM
clock’s sources are different for the ADuC841, and are given in
Table 17.

Figure 47. PWM Block Diagram
The PWM uses five SFRs: the control SFR (PWMCON) and
four data SFRs (PWM0H, PWM0L, PWM1H, and PWM1L).
PWMCON, as described in the following sections, controls the
different modes of operation of the PWM as well as the PWM
clock frequency.
PWM0H/L and PWM1H/L are the data registers that deter-
mine the duty cycles of the PWM outputs. The output pins that
the PWM uses are determined by the CFG841/CFG842 register,
and can be either P2.6 and P2.7 or P3.4 and P3.3. In this section
of the data sheet, it is assumed that P2.6 and P2.7 are selected as
the PWM outputs.
To use the PWM user software, first write to PWMCON to
select the PWM mode of operation and the PWM input clock.
Writing to PWMCON also resets the PWM counter. In any of
the 16-bit modes of operation (Modes 1, 3, 4, 6), user software
should write to the PWM0L or PWM1L SFRs first. This value is
written to a hidden SFR. Writing to the PWM0H or PWM1H
SFRs updates both the PWMxH and the PWMxL SFRs but does
not change the outputs until the end of the PWM cycle in
progress. The values written to these 16-bit registers are then
used in the next PWM cycle.
