System control register.
Writing ‘1’ to this bit causes a soft reset
Cleared by hardware.
Writing ‘1’ to this bit shuts down the I2C block on the next valid I2C clock.
In shut-down mode, only 2 possible ways exist to re-activate the device:
- Remove and reconnect Vcc
- Wake_up through the GPIO_0 pin if programmed as a hot-key and if Wakeup Enable bit of
this register is enabled
All GPIO states remain the same on entering shut-down mode.
Wakeup Enable bit
‘1’ to enable GPIO_0 as clock gating signal during shutdown
‘0’ to disable the above
‘1’ to enable interrupt output
‘0’ to disable interrupt output
When the interrupt output is disabled, it is in floating condition but it does not consume current
Interrupt polarity
‘1’ for active High
‘0’ for active LOW
