This section describes the configuration registers, CONFIG1 and
CONFIG2. The configuration registers enable or disable these options:
The configuration registers are used in the initialization of various
options. The configuration registers can be written once after each reset.
All of the configuration register bits are cleared during reset. Since the
various options affect the operation of the MCU, it is recommended that
these registers be written immediately after reset. The configuration
registers are located at $001E and $001F. The configuration register
may be read at anytime.
