Memory location: 02
Reset state: 000X X000
0: GPIO configured as input (default)
1: GPIO configured as open-drain output
GPIO DIRECTION, DIR
GPIO PORT BIT, GPIO
FLASH BLANKING, Tx-MASK
This bit contains the GPIO port value
This bit is only valid for DIR = 0
In write mode, this bit enables/disables the flash
blanking function.
0: Flash blanking is disabled (default)
1: LED current is reduced to torch current level
when GPIO = 1
In read mode, this flag indicates whether or not the
flashlight masking input has been activated.
Tx-MASK flag is reset after readout of the flag.
0: No flash blanking event occured
1: Flash blanking triggered
Refer to 3-Bit ADC section for more details.
ILIM[1:0] can only be written once whilst the device
is in shutdown.
00: 1000 mA (typ) (default)
01: 1500 mA (typ)
10: 1500 mA (typ)
11: 2000 mA (typ)
LED failure flag is reset after readout of the flag.
0: Proper LED operation
1: LED failed (open or shorted)
ADC OUTPUT , ADC[2:0] (READ ONLY)

Time-out flag is reset after readout of the flag.
0: Normal operation (default)
1: Thermal shutdown tripped

Setting bits 3, 4 and 5 (whilst MODE_CTRL[1:0]=01 or 10) starts an LED forward voltage measurement.
A write operation on bit 5 and 6 points to the ILIM[1:0] bits.
A read operation on bit 5 and 6 points to the LF and ADC[2] bits.
