C.1 Digital I/O
The F75111 provides one serial access interface, I2C Bus, to read/write
internal registers. The address of Serial Bus is 0x6E (0110_1110)
The related register for configuring DIO is list as follows:
Configuration and Control Register-Index 01h
Power-on default [7:0]=0000_1000b
Bit Name R/W PWR Description
7 INIT R/W VSB3V
Software reset for all registers
including Test Mode registers.
Users use only.
6 Reserved R/W VSB3V
5 EN_WDT10 R/W VSB3V
Enable Reset Out. If set to 1,
enable WDTOUT10# output.
Default is disable.

OWR_MAG
EMENT
R/W VSB3V
Set this bit to 1 will enable auto
power down mode, when all
function are idle then 20ms the
chip will auto power down, it will
wakeup when GPIO state change
or read write register
0

R/W VSB3V
Set this bit to 1 will power down all
of the analog block and stop
internal clock, write 0 to clear this
