SMR2 Register Events
P27 Stop
Select
This register is not reset after a Stop Mode Recovery.
The SMR2 register function is similar to the standard Stop Mode Recovery feature used in
previous Z8 CPU-compatible parts. Register bits SMR2[4:2] are set to select one of seven
event modes, as displayed in
compared to the state of SMR2[6]; when they are the same, a Stop Mode Recovery event
is generated. If SMR2[4:2]=000, no event source is selected by SMR2.
