Configuration Register (CONFIG)
5.1 Introduction
This section describes the configuration registers (CONFIG1 and CONFIG2). The configuration registers
enable or disable the following options:
5.2 Functional Description
The configuration registers are used in the initialization of various options. The configuration registers can
be written once after each reset. Most of the configuration register bits are cleared during reset. Since the
various options affect the operation of the microcontroller unit (MCU) it is recommended that this register
be written immediately after reset. The configuration registers are located at $001E and $001F, and may
be read at anytime.
