CIDL
Counter Idle control: CIDL = 0 programs the PCA Counter to continue functioning during idle Mode.
CIDL = 1 programs it to be gated off during idle.
WDTE
Watchdog Timer Enable: WDTE = 0 disables Watchdog Timer function on PCA Module 4. WDTE = 1
enables it.

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.

ECF
PCA Enable Counter Overflow interrupt: ECF = 1 enables CF bit in CCON to generate an interrupt.
ECF = 0 disables that function of CF.
