Configuration and Mask Option Registers (CONFIG & MOR) Freescale Semiconductor
STOP_XCLKEN — Crystal Oscillator Stop Mode Enable
OSCCLK1, OSCCLK0 — Oscillator Output Control Bits
CDOEN — Current-Flow Detect Output Enable
STOP_XCLKEN enables the crystal (x-tal) oscillator to continue
operating during stop mode. Setting the STOP_XCLKEN bit allows
the x-tal oscillator to operate continuously even during stop mode.
This is useful for driving the timebase module to allow it to generate
periodic wake up while in stop mode. (See
Generator Module (CGM)
Reset clears this bit.
OSCCLK1 and OSCCLK0 select which oscillator output to be driven
out as OSCCLK to the timebase module (TBM). Reset clears these
two bits.
CDOEN enables the port pin PC0/PWM0/CD as the CD output pin for
the current detect flag (CDIF) from the analog module. Reset clears
the CDOEN bit.
1 = X-tal oscillator enabled to operate during stop mode
0 = X-tal oscillator disabled during stop mode
1 = PCO/PWMO/CD pin enabled as CD output pin,
0 = PTC0/PWM/CD pin disabled as CD output pin,

PTC0 and PWM0 functions are disabled.
