Configuration & Mask Option Registers (CONFIG & MOR)
3.1 Introduction
This section describes the configuration registers, CONFIG1 and CONFIG2; and the mask option
register, MOR.
The configuration registers enable or disable these options:
The mask option register selects one of the following oscillator options:
