LOGIC BLOCK
Several of the ADP5586 input/output lines can be used as inputs
and outputs for implementing some common logic functions.
The R1, R2, and R3 input/output pins can be used as inputs,
and the R0 input/output pin can be used as an output for the
logic block. When the R1, R2, and R3 input lines are used, the
GPIO_4_INP_EN, GPIO_3_INP_EN, and GPIO_2_INP_EN
bits (Register 0x29, Bits[3:1]) must be enabled to accept inputs.
When the R0 pin is used as an output for the logic block, the
GPIO_1_OUT_EN bit (Register 0x27, Bit 0) must be enabled.
The outputs from the logic block can be configured to generate
interrupts. They can also be configured to generate events on
the FIFO.
Figure 19 shows a detailed diagram of the internal makeup of
the logic block, illustrating the possible logic functions that can
be implemented.
