4.2.2 Master Clear (MCLR) Pin

The MCLR pin provides for two specific device functions:

Device Reset
Device programming and debugging

Pulling the MCLR pin low generates a device Reset. Module Basic Connection and Interface Diagram illustrates a typical MCLR circuit, see the Module Basic Connection and Interface Diagram in the Basic Connection Requirement from Related Links.

The module has sufficient filtering (0.1 μF) and pull-up (10k) on the Reset line. On a typical application, no extra filtering is required on this pin.
