High Speed Output Mode
In this mode the CEX output (on port 1) associated with the PCA module will toggle
each time a match occurs between the PCA counter and the module
’
s capture registers.
To activate this mode the TOG, MAT, and ECOM bits in the module
’
s CCAPMn SFR
must be set (See Figure 27).
A prior write must be done to CCAPnL and CCAPnH before writing the ECOMn bit.
Figure 27.
PCA High Speed Output Mode
Before enabling ECOM bit, CCAPnL and CCAPnH should be set with a non zero value,
otherwise an unwanted match could happen.
Once ECOM is set, writing CCAPnL will clear ECOM so that an unwanted match doesn
’
t
occur while modifying the compare value. Writing to CCAPnH will set ECOM. For this
reason, user software should write CCAPnL first, and then CCAPnH. Of course, the
ECOM bit can still be controlled by accessing to CCAPMn register.
Pulse Width Modulator
Mode
All of the PCA modules can be used as PWM outputs. Figure 28 shows the PWM func-
tion. The frequency of the output depends on the source for the PCA timer. All of the
modules will have the same frequency of output because they all share the PCA timer.
The duty cycle of each module is independently variable using the module's capture
register CCAPLn. When the value of the PCA CL SFR is less than the value in the mod-
ule's CCAPLn SFR the output will be low, when it is equal to or greater than, the output
will be high. When CL overflows from FF to 00, CCAPLn is reloaded with the value in
CCAPHn. This allows updating the PWM without glitches. The PWM and ECOM bits in
the module's CCAPMn register must be set to enable the PWM mode.
