named CCF0 and CCF1 in SFR CCON. The CCF0 and CCF1 serve as flags for module-0 and
module-1 respectively. They are set by hardware when either a match or a capture occurs.
These flags also can only be cleared by software.
SFR: CCON (PCA Counter Control Rregister)
SFR: CMOD (PCA Mode Control Register)
CIDL:=Behavior control of the PCA.
{ CPS1, CPS0 } := Used to select the clocking source for PCA counter
ECF:=Control bit of deciding if to pass interrupt from PCA timer overflow to the MCU

1:=
{ 0, 0 } := set the frequency of the PCA counter clock source as oscillator’s frequency over
{ 0, 1 } := set the frequency of the PCA counter clock source as oscillator’s frequency over 2
{ 1, 0 } := set the PCA counter clock source as Timer-0 overflow
{ 1, 1 } := set the PCA counter clock source as pin ECI(pin P3.4)
Enable counting of the PCA counter while the MCU is put under idle state.
Permit the interrupt from PCA timer to the MCU
Disable counting of the PCA counter while the MCU is put under idle state.
Inhibit the interrupt from PCA timer to the MCU
