Digital I/O Control Register

0x0A

Bits Type Default Description

[15] WO 0 DIO(3) interrupt condition:

0 – interrupt on a rising edge;

1 – interrupt on a falling edge.

[14] WO 0 DIO(2) interrupt condition:

0 – interrupt on a rising edge;

1 – interrupt on a falling edge.

[13] WO 0 DIO(1) interrupt condition:

0 – interrupt on a rising edge;

1 – interrupt on a falling edge.

[12] WO 0 DIO(0) interrupt condition:

0 – interrupt on a rising edge;

1 – interrupt on a falling edge.

[11] WO 0 DIO group 2 mode:

0 – input;

1 – output.

[10] WO 0 DIO group 1 mode:

0 – input;

1 – output.

[9] UU X Reserved.

[8] WO 0 DIO group 2 interrupt condition:

0 – interrupt on a rising edge;

1 – interrupt on a falling edge.

[7:0] RW 0x00 Write operations set the bits configured as outputs, do not

affect the bits configured as inputs. Read operations return the

current values of the bits configured as inputs and last written

value of the bits configured as outputs. (Note 1).

Notes:

1. Enabling an interrupt on a DIO bit configured as output will result in the interrupt when the

interrupt condition is met: for example, if a DIO bit is configured as output, has an interrupt

configured on a rising edge and enabled, and its current state is 0, writing a 1 to this bit will

generate an interrupt.
