SMR3 Register Events
Reserved
Value
This register is not reset after a Stop Mode Recovery.
The SMR3 register can be used to configure one or more of Port 3, pins 0–3 to be
compared to a written or sampled reference value and generate a Stop Mode Recovery
event when the pin state differs from the reference value.
