I2C register map

GPIO_STANDBY

gpio_standby_en

PRW

STANDBY output enable (active

low)

0 = PAD configured as OUTPUT

1 = PAD configured as INPUT

gpio_standby_a

PRW

STANDBY data output (when

_en = 0)

gpio_standby_zi

STANDBY IO value

PWM_PERIOD

pwm_period

7:0

PRW

PWM period duration (20us tick

period)

PWM_PULSEHIGH0 pwm_pulse_high0

7:0

PRW

PWM0 pulse high duration

(20 us tick period) - 0 = disable

PWM_PULSEHIGH1 pwm_pulse_high1

7:0

PRW

PWM1 pulse high duration

(20 us tick period) - 0 = disable

PWM_PULSEHIGH2 pwm_pulse_high2

7:0

PRW

PWM2 pulse high duration

(20 us tick period) - 0 = disable

CLOCKS_LO

clk_motion_timer

PRW

Timer clock enabled (forced

always on)

clk_pci_en

PRW

PCI clock enable (forced always

on)

clk_framedump_en

PRW

Framedump clock enable

(forced always on)

RESETS

software_reset_n

PRWC

Software reset result in full

system reboot (active low - auto

cleared)

Reserved

4:1

PRW

Do not modify these bits.

framedump_reset_n

PRW

Framedump reset signal (active

low)

Reserved

7:6

PRW

Do not modify these bits.

CONTROL

motion_engine_start

PRW

Timer interrupt enable. This

enables the Motion timer to

operate. Motion timer generates

pulses that trigger frame

capture and motion processing.
