MEGAWIN
CF bit (CCON.7) will be set when the PCA timer overflows, and an interrupt will be generated
if the ECF (CMOD.0) is set. The CF bit can only be cleared by software. There are four bits
named CCF0, CCF1, CCF2 and CCF3 in SFR CCON. Those bits serve as flags for module-0,
module-1, module-2, and module-3 respectively. They are set by hardware when either a
match or a capture occurs. These flags also can only be cleared by software.
SFR: CMOD (PCA Counter Mode Register)
SFR: CCON (PCA Counter Control Register)
IDLE
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

0:= (default)
1:=
{ 0, 0 }:= set the frequency of the PCA counter clock source as oscillator’s frequency over 12
{ 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)
0:= (default)
