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.
Watchdog Timer Enable: WDTE = 0 disables Watchdog Timer function on PCA Module 4. WDTE = 1 enables it.
Not implemented, reserved for future use.*

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.

CF
PCA Counter Overflow flag. Set by hardware when the counter rolls over. CF flags an interrupt if bit ECF in CMOD is
set. CF may be set by either hardware or software but can only be cleared by software.
PCA Counter Run control bit. Set by software to turn the PCA counter on. Must be cleared by software to turn the PCA
counter off.
Not implemented, reserved for future use*.
PCA Module 4 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by software.
PCA Module 3 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by software.
PCA Module 2 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by software.
PCA Module 1 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by software.
PCA Module 0 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by software.
