The logic configured by the SMR2 register ignores any port pins that are configured as an
output, or that are selected as source pins in registers SMR1 or SMR3. The SMR2 register
is summarized in
Figure 46. SMR2 Register-Controlled Event Sources
SMR2[6]
Table 71
on page 152.
This SMR2 register logic ignores any pin configured
as an output in the P2M or P3M registers or
as a source in the SMR1 or SMR3 registers.
