Port A–C Stop Mode Recovery Source Enable Subregisters
The Port A–C Stop Mode Recovery Source Enable Subregister (Table 26) is accessed
through the Port A–C Control Register by writing 05H to the Port A–C Address Register.
Setting the bits in the Port A–C Stop Mode Recovery Source Enable subregisters to 1 con-
figures 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.
