bit 0

Legend:

W = Writable bit

‘0’ = Bit is cleared

R = Readable bit

‘1’ = Bit is set

x = Bit is unknown

-n = Value at POR

U = Unimplemented bit

P = Programmable Bit

bit 13

1

= ON

- Low-voltage programming enabled

0

= OFF

bit 12

1

= OFF

- In-circuit debugger is disabled

0

= ON

- In-circuit debugger is enabled

bit 11

LPBOR: Low-Power BOR bit

1

= OFF

- Low-Power BOR is disabled

0

= ON

- Low-Power BOR is enabled

bit 10

BORV: Brown-out Reset Voltage Selection bit

1

= LOW

0

bit 9

STVREN: Stack Overflow/Underflow Reset Enable bit

1

= ON

- Stack Overflow or Underflow will cause a Reset

0

= OFF

- Stack Overflow or Underflow will not cause a Reset

bit 8

PLLEN: PLL Enable bit

1

= ON

- 4x PLL will be enabled for external clock, if FOSC = EC, or for INTOSC, if IRCF = 8 MHz or 16 MHz

0

= OFF

- 4x PLL disabled

bit 7

ZCD: ZCD Disable bit

1

= OFF

- ZCD disabled. ZCD can be enabled by setting the ZCDSEN bit of ZCDCON

0

= ON

- ZCD always enabled

bit 6-3

Unimplemented: Read as ‘1’

Note

1:

The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.

2:

3:

This bit is only implemented on the PIC16(L)F1614/5/8/9. It acts as Unimplemented: Read as '1' on all other parts in

the family.

REGISTER 3-3:

CONFIGURATION WORD 1 (CONTINUED)

Note

1:

Enabling Brown-out Reset does not automatically enable Power-up Timer.

2:

The entire program memory will be erased when the code protection is turned off.

3:

This bit should be maintained as ‘1’ when programmed.

4:

These bits are only implemented on the PIC16(L)F1615/9. They act as Unimplemented: Read as ‘1’ on all other parts

in the family.

5:

This bit is forced to ‘1’ on the PIC12(L)F1612 and PIC16(L)F1613/4/8.
