Bit Masks and Bit Field Masks

Register bits can be manipulated using predefined masks, or bit positions. The predefined bit masks from the header file are either related to individual bits, called a bit mask, or related to a bit field, called a bit field mask.

A bit mask is used both when setting and clearing individual bits. A bit field mask is mainly used when clearing multiple bits in a bit field.

For the ADCON2 register, the bit fields, bit names, bit positions, and bit masks of this register, see the table below.
