When set to ‘1’, this bit indicates that an internal reset occurred.
0 indicates the last system reset was not internal reset
1 indicates the last system reset was internal reset
This bit indicates whether factory defaults are loaded during power-up.
0 User default configuration is loaded during power-up
1 Factory default configuration is loaded during power-up
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 Functionality of CapSense block is disabled
1 Functionality of CapSense block is enabled
This bit indicates whether GP Output function is enabled or disabled.
0 Functionality of Digital output block is disabled
1 Functionality of Digital output block is enabled
