Port A–H Stop Mode Recovery Source Enable Subregisters
The Port A–H Stop Mode Recovery Source Enable Subregister, shown in Table 20, is
accessed through the Port A–H Control Register by writing 05H to the Port A–H Address
Register. Setting the bits in the Port A–H Stop Mode Recovery Source Enable subregisters
to 1 configures the specified Port pins as a Stop Mode Recovery source. During STOP
Mode, any logic transition on a Port pin enabled as a Stop Mode Recovery source initiates
Stop Mode Recovery.
