5.4 Configuration Register 1 (CONFIG1)
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
†† Reset by POR only.
Address:
The CONFIG1 register can be written once after each reset.
COPRS — COP Rate Select
LVISTOP — LVI Enable in Stop Mode
LVIRSTD — LVI Reset Disable
LVIPWRD — LVI Power Disable Bit

Write:
COPRS selects the COP time-out period. Reset clears COPRS. (See
Section 21. Computer Operating Properly
When the LVIPWRD bit is clear, setting the LVISTOP bit enables the
LVI to operate during stop mode. Reset clears LVISTOP. (See
Section 22. Low-Voltage Inhibit
LVIRSTD disables the reset signal from the LVI module. (See
Section 22. Low-Voltage Inhibit
LVIPWRD disables the LVI module. (See
Inhibit
