TRGAM Trigger edge acceptance control
TRGSEL Select a trigger start edge.
PPGC2INI
Specify the initial value of PPG2
output.
PPGC1INI
Specify the initial value of PPG1
output.
NCRSEL
Select the duration of noise elimi-
nation for TCC0 input
(after passing through the flip-flop).
TCCCK Select a source clock
0: Always accept trigger edges.
1: (Refer to the setting of TC0CR2<PPGC2OE, PPGC1OE>)
0: Start on trigger falling edge.
1: Start on trigger rising edge.
0: Low (Positive logic)
1: High (Negative logic)
0: Low (Positive logic)
1: High (Negative logic)
00: Eliminate pulses shorter than 16/fcgck [s] as noise.
01: Eliminate pulses shorter than 8/fcgck [s] as noise.
10: Eliminate pulses shorter than 4/fcgck [s] as noise.
11: Do not eliminate noise. (Note)
00: fcgck [Hz]
01: fcgck/2 [Hz]
10: fcgck/2² [Hz]
11: fcgck/2³ [Hz]
Note:Due to the circuit configuration, a pulse shorter than 1/fcgck may be eliminated as noise or accepted as a trig-
ger.
