Description
0 = 300 kΩ resistor used for row pull-up during key scanning.
1 = 100 kΩ resistor used for row pull-up during key scanning.
0 = C0 remains configured as GPIO 7.
1 = C0 reconfigured as PULSE_GEN_1 output.
0 = R4 remains configured as GPIO 5.
1 = R4 reconfigured as RESET_OUT output.
0 = C1 remains configured as GPIO 8.
1 = C1 reconfigured as PULSE_GEN_2 output.
0 = R3 remains configured as GPIO 4.
1 = R3 reconfigured as LC input for the logic block.
Reserved.
0 = R0 remains configured as GPIO 1.
1 = R0 reconfigured as LY output from the logic block.
Description
0 = disables internal 800 kHz oscillator.
1 = enables internal 800 kHz oscillator.
Sets the input clock frequency fed from the base 800 kHz oscillator to the digital core. Slower
frequencies result in less quiescent current, but key and GPI scan times increase.
00 = 50 kHz.
01 = 100 kHz.
10 = 200 kHz.
11 = 400 kHz.
Reserved.
Software reset. Set to 1 to reset the ADP5586. This function is similar to bringing RST low, then
high. Wait at least 200 μs before reprogramming the device.
Configures the behavior of the INT pin if the user tries to clear it while an interrupt is pending.
0 = INT pin remains asserted if an interrupt is pending.
1 = INT pin deasserts for 50 μs and reasserts if an interrupt is pending.
