R/W Input Edge Select B
Selects the rising or falling edge of the input capture B
signal (FTIB).
0: Capture on the falling edge of FTIB
1: Capture on the rising edge of FTIB
R/W Input Edge Select C
Selects the rising or falling edge of the input capture C
signal (FTIC).
0: Capture on the falling edge of FTIC
1: Capture on the rising edge of FTIC
R/W Input Edge Select D
Selects the rising or falling edge of the input capture D
signal (FTID).
0: Capture on the falling edge of FTID
