    The CIDL bit which allows the PCA to stop during idle mode.
    The WDTE bit which enables or disables the watchdog function on module 4.
    The ECF bit which when set causes an interrupt and the PCA overflow flag CF (in the CCON
    SFR) to be set when the PCA timer overflows.
    The CCON SFR
    contains the run control bit for the PCA and the flags for the PCA timer (CF)
    and each module (Refer to Table 6-5).
    Bit CR (CCON.6) must be set by software to run the PCA. The PCA is shut off by clearing this
    bit.
    Bit CF: The CF bit (CCON.7) is set when the PCA counter overflows and an interrupt will be
    generated if the ECF bit in the CMOD register is set. The CF bit can only be cleared by
    software.
    Bits 0 through 4 are the flags for the modules (bit 0 for module 0, bit 1 for module 1, etc.) and
    are set by hardware when either a match or a capture occurs. These flags also can only be
    cleared by software.
    Table 6-5.
    CCON: PCA Counter Control Register
    The watchdog timer
    function is implemented in module 4 (See Figure 6-7).
    The PCA interrupt
    system is shown in Figure 6-5.

    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.
    CR
    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.

    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.
    CCF4
    PCA Module 4 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by
    software.
    CCF3
    PCA Module 3 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by
    software.
    CCF2
    PCA Module 2 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by
    software.
    CCF1
    PCA Module 1 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by
    software.
    CCF0
    PCA Module 0 interrupt flag. Set by hardware when a match or capture occurs. Must be cleared by
    software.
