COPD — COP Disable Bit

COPD disables the COP module. (See Section 21. Computer

Operating Properly (COP).)

1 = COP module disabled

0 = COP module enabled

5.4 Configuration Register 2 (CONFIG2)

STOP_ICLKDIS — Internal Oscillator Stop Mode Disable

STOP_ICLKDIS disables the internal oscillator during stop mode.

Setting the STOP_ICLKDIS bit disables the oscillator during stop

mode. (See Section 7. Oscillator (OSC).)

Reset clears this bit.

1 = Internal oscillator disabled during stop mode

0 = Internal oscillator enabled to operate during stop mode

STOP_RCLKEN — RC Oscillator Stop Mode Enable 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 Section 7. Oscillator (OSC).)

Reset clears this bit.

1 = RC oscillator enabled to operate during stop mode

0 = RC oscillator disabled during stop mode
