BIT 4 USR5.0 Polarity
Bit 4 determines which edge or level is used in the wakeup detection circuit. A low level selects a rising
transition and the true pin value of USR5.0 to the wakeup detection circuit. When this bit is set to a 1, a falling
transition and complemented USR5.0 value is presented to the wakeup detection circuit.
BIT 3 USR5.1 Polarity
Bit 3 determines which edge or level is used in the wakeup detection circuit. A low level selects a rising
transition and the true pin value of USR5.1 to the wakeup combinatorial circuit. When this bit is set to a 1, a
falling transition and complemented USR5.1 value is presented to the wakeup detection circuit.
BIT 2 USR5.0 Edge Activity Enabled
When bit 2 is set to a 1, a transition of USR5.0 of the appropriate level as dictated by bit 4, will wake up the
processor. If this bit is reset to a 0, edge activity on this pin is ignored.
BIT 1 USR5.1 Edge Activity Enabled
When bit 1 is set to a 1, a transition of USR5.0 of the appropriate level as dictated by bit 3, will wake up the
processor. If this bit is reset to a 0, edge activity on this pin is ignored.
BIT 0 Combinatorial AND of USR5.0 and USR5.1 Level Enabled
When bit 0 is set to a 1, the value USR5.0 or its complimented value as dictated by bit 3, AND’ed with the value
USR5.1 or its complimented value as dictated by bit 2, will wake up the processor. If this bit is reset to a 0, the
levels of USR5.0 and USR5.1 are ignored.
