Stop-Mode Recovery Register 2 (SMR2)
Figure 42. Stop-Mode Recovery Register 2—(0F) DH: D2–D4, D6 Write Only
SMR2 (0F) DH
Note:
This register (see
SMR2.
If SMR2 is used in conjunction with SMR, either of the specified events causes a
Stop-Mode Recovery.
D7 D6 D5 D4 D3 D2 D1 D0
Note: If used in conjunction with SMR,
either of the two specified events
causes a Stop-Mode Recovery.
* Default setting after reset
Port pins configured as outputs are ignored as a SMR or SMR2
recovery source. For example, if the NAND of 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.
