Calibration Words

The internal calibration values are factory calibrated and stored in Calibration Words 1, 2 and 3 (800Ah, 800Bh and

800Ch).

The Calibration Words do not participate in erase operations. The device can be erased without affecting the Calibration

Words.

1

= ON

- Fail-Safe Clock Monitor is enabled

0

= OFF

- Fail-Safe Clock Monitor is disabled

- PWRT enabled

bit 4-3

Unimplemented: Read as ‘1’

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.
