9. 8-Bit Timers
Bits 3 and 2—Output/Input Capture Edge Select B3 and B2 (OIS3, OIS2): In combination
with the ICE bit in 8TCSR1 (8TCSR3), these bits select the compare match B output level or the
input capture input detected edge.
The function of TCORB1 (TCORB3) depends on the setting of bit 4 of 8TCSR1 (8TCSR3).
