PULSEWIDTH MODULATOR (PWM)
The PWM on the ADuC836 is a highly flexible PWM offering
programmable resolution and input clock, and can be configured
for any one of six different modes of operation. Two of these modes
allow the PWM to be configured as a
-
DAC with up to 16 bits
of resolution. A block diagram of the PWM is shown in Figure 26.

Reserved for Future Use
The PWM uses five SFRs: the control SFR, PWMCON, and
four data SFRs: PWM0H, PWM0L, PWM1H, and PWM1L.
PWMCON (as described in Table XVI) controls the different
modes of operation of the PWM as well as the PWM clock fre-
quency. PWM0H/L and PWM1H/L are the data registers that
determine the duty cycles of the PWM outputs at P1.0 and P1.1.
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.
