13.3.7 COPRS (COP Rate Select)
The COPRS signal reflects the state of the COP rate select bit (COPRS) in the configuration register 1.
COPRS — COP Rate Select Bit
COPD — COP Disable Bit
13.4 COP Control Register
The COP control register is located at address $FFFF and overlaps the reset vector. Writing any value to
$FFFF clears the COP counter and starts a new timeout period. Reading location $FFFF returns the low
byte of the reset vector.
13.5 Interrupts
The COP does not generate CPU interrupt requests.
13.6 Monitor Mode
The COP is disabled in monitor mode when V
13.7 Low-Power Modes
The WAIT and STOP instructions put the MCU in low-power consumption standby modes.
Freescale Semiconductor
COPRS selects the COP timeout period. Reset clears COPRS.
COPD disables the COP module.
1 = COP timeout period is 8176 × 2OSCOUT cycles
0 = COP timeout period is 262,128 × 2OSCOUT cycles
1 = COP module disabled
0 = COP module enabled
