Description
Not used
Drive strength control for I/O pins in output mode. Selects output
drive capability to account for low I/O supply voltage on pin DVDD
(this to ensure same drive strength at lower voltages as is on
higher).
0 Minimum drive capability. DVDD equal or greater than 2.6V
1 Maximum drive capability. DVDD less than 2.6V
Port 2, inputs 4 to 0 interrupt enable. This bit enables interrupt
requests for the port 2 inputs 4 to 0.
0 Interrupts are disabled
1 Interrupts are enabled
Port 0, inputs 7 to 4 interrupt enable. This bit enables interrupt
requests for the port 0 inputs 7 to 4.
0 Interrupts are disabled
1 Interrupts are enabled
Port 0, inputs 3 to 0 interrupt enable. This bit enables interrupt
requests for the port 0 inputs 3 to 0.
0 Interrupts are disabled
1 Interrupts are enabled
Port 2, inputs 4 to 0 interrupt configuration. This bit selects the
interrupt request condition for all port 2 inputs
0 Rising edge on input gives interrupt
1 Falling edge on input gives interrupt
Port 1, inputs 7 to 0 interrupt configuration. This bit selects the
interrupt request condition for all port 1 inputs
0 Rising edge on input gives interrupt
1 Falling edge on input gives interrupt
Port 0, inputs 7 to 0 interrupt configuration. This bit selects the
interrupt request condition for all port 0 inputs
0 Rising edge on input gives interrupt
1 Falling edge on input gives interrupt
