#
The configuration registers and the mask option register are used in the
initialization of various options. These two types of registers are
configured differently:
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 $001D and $001F. The configuration registers may be
read at anytime.
The CONFIG registers are not in the FLASH memory but are special
registers containing one-time writable latches after each reset. Upon a
reset, the CONFIG registers default to predetermined settings as shown
in
