5.5 Configuration Register 2 (CONFIG2)
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor Configuration and Mask Option Registers (CONFIG & MOR)
Address:
STOP — STOP Instruction Enable
COPD — COP Disable Bit
STOP_ICLKEN — Internal Oscillator Stop Mode Disable
STOP_RCLKEN — RC Oscillator Stop Mode Enable
Reset:
Read: STOP_
Write:
STOP enables the STOP instruction.
COPD disables the COP module. (See
Operating Properly
STOP_ICLKEN disables the internal oscillator during stop mode.
Setting the STOP_ICLKEN bit disables the oscillator during stop
mode. (See
Reset clears this bit.
STOP_RCLKEN enables the RC oscillator to continue operating
during stop mode. Setting the STOP_RCLKEN bit allows the
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
Module (CGM)
Reset clears this bit.
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
1 = COP module disabled
0 = COP module enabled
1 = Internal oscillator disabled during stop mode
0 = Internal oscillator enabled to operate during stop mode
