D7
Note: If used in conjunction with SMR, either of the two specified events causes a Stop Mode Recovery.
* Default setting after reset.
* * At the XOR gate input.

D5
Stop Mode Recovery Register 2 (SMR2)
This register determines the mode of Stop Mode Recovery for SMR2
SMR2(0F)DH
If SMR2 is used in conjunction with SMR, either of the specified events causes a Stop
Mode Recovery.
Port pins configured as outputs are ignored as an SMR or SMR2 recovery source. For
example, if the NAND or P23–P20 is selected as the recovery source and P20 is config-
ured as an output, the remaining SMR pins (P23–P21) form the NAND equation.
