EDGnB, EDGnA — Input Capture Edge Control
To operate the 16-bit pulse accumulators A and B (PACA and PACB)
independently of input capture or output compare 7 and 0 respectively
the user must set the corresponding bits IOSn = 1, OMn = 0 and OLn
= 0. OC7M7 or OC7M0 in the OC7M register must also be cleared.
These eight pairs of control bits configure the input capture edge
detector circuits.
