Not implemented, reserved for future use*.
Enable Comparator. ECOM = 1 enables the comparator function.
Capture Positive, CAPP = 1 enables positive edge capture.
Capture Negative, CAPN = 1 enables negative edge capture.
Match. When MAT = 1, a match of the PCA counter with this module’s compare/capture register causes the CCF bit in
CCON to be set, flagging an interrupt.
Toggle. When TOG = 1, a match of the PCA counter with this module’s compare/capture register causes the CEX pin
to toggle.
Pulse Width Modulation Mode. PWM4 = 1 enables the CEX pin to be used as a pulse width modulated output.
Enable CCF interrupt. Enables compare/capture flag CCF in the CCON register to generate an interrupt.

NOTE:
*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.
