CCU2 Capture input source 2
CCU2 = 0 - external Pin to be CCU2 capture input source
CCU2 = 1 - analog comparator 1 output to be CCU2 capture input source
CCU1 Capture input source 1
CCU1= 0 - external Pin to be CCU1 capture input source
CCU1= 1 - analog comparator 0 output to be CCU1 capture input source
CCUINF[1:0] CCU capture input Noise Filter(CCU1,CCU2)
CCUINF[1:0] = 00 - 1 consecutive same value recognize as valid data.
CCUINF[1:0] = 01 - 2 consecutive same value recognize as valid data.
CCUINF[1:0] = 10 - 4 consecutive same value recognize as valid data.
CCUINF[1:0] = 11 - 8 consecutive same value recognize as valid data.
P42CC [1:0] Capture/Compare port select function.
00: Capture/Compare function on Port1.
01: Capture/Compare function on Port2
10: Capture/Compare function on Port4 (The TQFP 64L Package Only)
