SYSTEM_CONFIG

automatic_power_

mode

0PRW

Power mode scheme

0 = Manual

1 = Automatic

motion_pin_polarity

PRW

MOTION pin polarity (in non

IDLE system state)

0 = MOTION pin LOW when

motion detected

1 = MOTION pin HIGH when

motion detected

host_config_done

PRW

Bit needs to be set by host

when configured after power up.

use_standby_pin

PRW

STANDBY pin is used as chip

select to enable I2C in AUTO

power mode and STANDBY pin

is used to wake up the

OSC/DVREG (in sleep states in

auto power mode).

0 = STANDBY pin not used

1 = STANDBY pin is used

system_state

7:5

Legacy register - please use

system_state (0x91) instead.

GPIO_I2CSEL0

gpio_i2csel0_en

PRW

I2CSEL0 output enable (active

low)

0 = PAD configured as OUTPUT

1 = PAD configured as INPUT

gpio_i2csel0_a

PRW

I2CSEL0 data output (when _en

= 0)

gpio_i2csel0_zi

I2CSEL0 IO value

gpio_i2csel0_pd

PRW

I2CSEL0 pull-down control

(internal 35 kOhms pull-down

resistor) - active LOW

0 = IO is pulled down

1 = IO not pulled down
