The configuration registers are used in the initialization of various
options. 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 one-time writable by the user after each
reset. These 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
Although the LVISEL[1:0] bits default to predetermined setting of
LVISEL[1:0] = 0:1 by a POR only, these bits can still be written once after
each reset other than POR.
