Note:

The DEBUG bit in the Configuration Word 2 is managed automatically by device development tools, including debuggers and programmers. For normal device operation, this bit needs to be maintained as a ‘1’.
See the V_BOR parameter in the “Electrical Specifications” chapter for specific trip point voltages.

`1`	Background debugger disabled
`0`	Background debugger enabled

Bit 12 – STVREN Stack Overflow/Underflow Reset Enable bit

Value	Description
`1`	Stack Overflow or Underflow will cause a Reset
`0`	Stack Overflow or Underflow will not cause a Reset

Bit 11 – PPS1WAY PPSLOCKED bit One-Way Set Enable bit

Value	Description
`1`	The PPSLOCKED bit can be cleared and set only once; the PPS registers remain locked after one clear/set cycle
`0`	The PPSLOCKED bit can be set and cleared repeatedly (subject to the unlock sequence)

Bit 10 – ZCD ZCD Control bit

Value	Description
`1`	ZCD disabled. ZCD can be enabled by setting the ZCDSEN bit of the ZCDCON register.
`0`	ZCD always enabled, the ZCDSEN bit is ignored

Bit 9 – BORV Brown-out Reset Voltage Selection bit⁽²⁾

Value	Description
`1`	Brown-out Reset voltage (V_BOR) set to lower trip point level
`0`	Brown-out Reset voltage (V_BOR) set to higher trip point level

Bits 7:6 – BOREN[1:0] Brown-out Reset Enable bits

When enabled, Brown-out Reset Voltage (V_BOR) is set by the BORV bit

Value	Description
`11`	Brown-out Reset enabled, the SBOREN bit is ignored
