6.2 CONFIG2

Configuration Word 2

Note:

The DEBUG bit is managed automatically by device development tools including debuggers and programmers. For normal device operation, this bit needs to be maintained as a ‘1’.
The higher voltage selection is recommended for operation at or above 16 MHz.
The REFRNG bit is not available on the internal-only DAC (DAC2).
When enabled, Brown-out Reset voltage (V_BOR) is set by the BORV bit.

Bit 13 – DEBUG Debugger Enable⁽¹⁾

Value	Description
1	Background debugger disabled
0	Background debugger enabled

Bit 12 – STVREN Stack Overflow/Underflow Reset Enable

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 One-Way Set Enable

Value	Description
1	The PPSLOCKED bit can only be set once after an unlocking sequence is executed; once PPSLOCKED is set, all future changes to PPS registers are prevented
0	The PPSLOCKED bit can be set and cleared as needed (unlocking sequence is required)

Bit 10 – ZCD Zero-Cross Detect Disable

Value	Description
1	ZCD disabled, ZCD can be enabled by setting the ZCDSEN bit of ZCDCON
0	ZCD always enabled, the PMDx [ZCDMD] bit is ignored

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

Value	Description
1	Brown-out Reset voltage (V_BOR) set to 1.9V
0	Brown-out Reset voltage (V_BOR) set to 2.65V

Bit 8 – DACAUTOEN DAC Buffer Automatic Range Select Enable⁽³⁾

Value	Description
1	DAC Buffer reference range is determined by the REFRNG bit of DACxCON
0	DAC Buffer reference range is automatically determined by module hardware

Bits 7:6 – BOREN[1:0] Brown-out Reset (BOR) Enable⁽⁴⁾

Value	Description
11	Brown-out Reset enabled, the SBOREN bit is ignored
10	Brown-out Reset enabled while running, disabled in Sleep; the SBOREN bit is ignored
01	Brown-out Reset enabled according to SBOREN
00	Brown-out Reset disabled

Bit 5 – LPBOREN Low-Power BOR Enable

Value	Description
1	Low-Power BOR disabled
0	Low-Power BOR enabled

Bits 2:1 – PWRTS[1:0] Power-Up Timer (PWRT) Selection

Value	Description
11	PWRT disabled
10	PWRT is set at 64 ms
01	PWRT is set at 16 ms
00	PWRT is set at 1 ms

Bit 0 – MCLRE Master Clear (MCLR) Enable

Value	Name	Description
x	If LVP = `1`	MCLR pin is MCLR
1	If LVP = `0`	MCLR pin is MCLR
0	If LVP = `0`	MCLR pin function is port-defined function

The DEBUG bit is managed automatically by device development tools including debuggers and programmers. For normal device operation, this bit needs to be maintained as a ‘1’. The higher voltage selection is recommended for operation at or above 16 MHz. The REFRNG bit is not available on the internal-only DAC (DAC2). When enabled, Brown-out Reset voltage (VBOR) is set by the BORV bit.
