Bit(s) Bit Name Access Description

5 R4_ EXTEND_CFG Read/write 0 = R4 remains configured as GPIO 5.

1 = R4 reconfigured as RESET1 output.

4 N/A Reserved.

3 to 2 R3_EXTEND_CFG[1:0] Read/write 00 = R3 remains configured as GPIO 4.

01 = R3 reconfigured as LC input for the logic block.

10 = R3 reconfigured as PWM_OUT output from PWM block.

11 = unused.

N/A

Reserved.

0 R0_ EXTEND_CFG Read/write 0 = R0 remains configured as GPIO 1.

1 = R0 reconfigured as LY output from the logic block.

GENERAL_CFG Register 0x3B

Table 67. GENERAL_CFG Bit Descriptions

Bit(s) Bit Name Access Description

7 OSC_EN

Read/write

0 = disable internal 1 MHz oscillator.

1 = enable internal 1 MHz oscillator.

6 to 5

OSC_FREQ[1:0]

Read/write

Sets the input clock frequency fed from the base 1 MHz 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 = 500 kHz.

4 to 2

N/A Reserved.

INT

_CFG

Read/write

Configure 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.

RST

_CFG

R/W

Configure the response ADP5585 has to the

RST

pin.

0 = ADP5585 resets if

RST

is low.

1 = ADP5585 does not reset if

RST

is low.

INT_EN Register 0x3C

Table 68. INT_EN Bit Descriptions

Bit(s) Bit Name Access Description

7 to 5 N/A Reserved.

4 LOGIC_IEN Read/write

0 = Logic 1 interrupt is disabled.

1 = assert the

INT

pin if LOGIC_INT is set.

3 N/A Reserved.

2 OVRFLOW_IEN Read/write

0 = overflow interrupt is disabled.

1 = assert the

INT

pin if OVRFLOW_INT is set.

1 GPI_IEN Read/write

0 = GPI interrupt is disabled.

1 = assert the

INT

pin if GPI_INT is set.

0 EVENT_IEN Read/write

0 = event interrupt is disabled.

1 = assert the

INT

pin if EVENT_INT is set.
