Configuration Register (CONFIG)
6.1 Introduction
This section describes the configuration registers, CONFIG1 and CONFIG2. The configuration registers
enable or disable these options:
6.2 Functional Description
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.

Reset:
On a FLASH device, the options except LVI5OR3 are one-time writeable
by the user after each reset. The LVI5OR3 bit is one-time writeable by the
user only after each POR (power-on reset). The CONFIG registers are not
in the FLASH memory but are special registers containing one-time
writeable latches after each reset. Upon a reset, the CONFIG registers
default to predetermined settings as shown in
