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

Note:
Stop-Mode Recovery Register 2 (SMR2)
This register determines the mode of Stop-Mode Recovery for SMR2 (Figure 37).
SMR2 (0F) DH
Figure 37. Stop-Mode Recovery Register 2 ((0F) DH:D2–D4, D6 Write Only)
If SMR2 is used in conjunction with SMR, either of the specified events causes a
Stop-Mode Recovery.

D3
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 configured as an
output, the remaining SMR pins (P23–P21) form the NAND
equation.
