The last bit in the register ECOM (CCAPMn.6) when set enables the comparator function.
Table 6-7 shows the CCAPMn settings for the various PCA functions.

Not implemented, reserved for future use.

1.
User software should not write 1s to reserved bits. These bits may be used in future 8051 family
products to invoke new features. In that case, the reset or inactive value of the new bit will be 0,
and its active value will be 1. The value read from a reserved bit is indeterminate.
ECOMn
Enable Comparator. ECOMn = 1 enables the comparator function.
CAPPn
Capture Positive, CAPPn = 1 enables positive edge capture.
CAPNn
Capture Negative, CAPNn = 1 enables negative edge capture.
MATn
Match. When MATn = 1, a match of the PCA counter with this module's compare/capture register
causes the CCFn bit in CCON to be set, flagging an interrupt.
TOGn
Toggle. When TOGn = 1, a match of the PCA counter with this module's compare/capture register
causes the CEXn pin to toggle.
PWMn
Pulse Width Modulation Mode. PWMn = 1 enables the CEXn pin to be used as a pulse width
modulated output.
ECCFn
Enable CCF interrupt. Enables compare/capture flag CCFn in the CCON register to generate an
interrupt.
