Interface

Control

USE_DEV_PINS

Selects which pins to use for the 2-wire control:

0 = Use 2-wire I/F pins as 2-wire interface

1 = Use GPIO 10 and 11 as 2-wire interface, e.g.

to download settings from PIC.

Only applies when CONFIG pins[1:0] = 00.

Reset by state machine.

14:13

DEV_ADDR[1:0]

Selects device address (only valid when

CONF_STS = 00)

00 = 0x34

01 = 0x36

10 = 0x3C

11 = 0x3E

Reset by state machine.

CONFIG_DONE

Tells the system that the PIC micro has

completed its programming.

0 = Programming still to be done

1 = Programming complete

Only applies when CONFIG pins[1:0] = 00.

Reset by state machine.

RECONFIG_AT_ON

Selects whether to reset the registers in the OFF

state and whether to reload the device

configuration from the PIC when an ON event

occurs.

0 = Do not reset registers in the OFF state. Do not

load configuration data when an ON event occurs.

1 = Reset registers in the OFF state. Load

configuration from the PIC when an ON event

occurs.

Note that, in development mode, the device

configuration from the PIC is always loaded when

first powering up the chip.

This bit must always be set to default (1) in

Custom Modes 01, 10 and 11.

AUTOINC

Enables address auto-increment

0 = disabled

1 = enabled

Reset by state machine.

SPI_CFG

Controls the SDOUT (GPIO6) pin operation in 4

wire mode

0 = SDOUT output is CMOS

1 = SDOUT output is open drain

Note: SPI_4WIRE must be set for this to take

effect.

Protected by security key. Default held in metal
