EXTCLKEN — External Clock Enable Bit
OSCENINSTOP — Oscillator Enable In Stop Mode Bit
COPRS — COP Rate Select Bit
LVISTOP — LVI Enable in Stop Mode Bit
LVIRSTD — LVI Reset Disable Bit
Freescale Semiconductor
EXTCLKEN
EXTCLKEN enables an external clock source or crystal/ceramic resonator to be used as a clock input.
Setting this bit enables PTE4/OSC1 pin to be a clock input pin. Clearing this bit (default setting) allows
the PTE4/OSC1 and PTE3/OSC2 pins to function as a general-purpose input/output (I/O) pin. Refer
to
(ICG) Module)
OSCENINSTOP, when set, will enable the internal clock generator module to continue to generate
clocks (either internal, ICLK, or external, ECLK) in stop mode. See
(ICG)
stops. See
ICLK and ECLK will be forced low during stop mode. The default state for this option is clear, disabling
the ICG in stop mode.
COPD selects the COP timeout period. Reset clears COPRS. See
Properly (COP) Module
When the LVIPWRD bit is clear, setting the LVISTOP bit enables the LVI to operate during stop mode.
Reset clears LVISTOP.
LVIRSTD disables the reset signal from the LVI module. See
