Reset:
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 $001F and $003F. The configuration register
may be read at anytime.
LVISTOP — LVI Enable in Stop Mode Bit
LVIRSTD — LVI Reset Disable Bit
Read:
Write:
When the LVIPWRD bit is clear, setting the LVISTOP bit enables the
LVI to operate in stop mode. Reset clears LVISTOP. (See
21. Low-Voltage Inhibit
LVIRSTD disables the reset signal from the LVI module. (See
Section 21. Low-Voltage Inhibit
