These bits contain the device and product ID.
Supply voltage is automatically detected and these bits are set accordingly.
When set to ‘1’, this bit indicates that an internal reset occurred.
0

1
When set to ‘1’, this bit indicates that the supply voltage applied to the device Is too
low for a write to nonvolatile memory operation, and no write is performed. This bit
must be checked before any Store or Write POR command.
This bit indicates whether CapSense function is enabled or disabled.
0
1
This bit indicates whether GP Output function is enabled or disabled.
