Product Specification

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.
