19.3.8 COPRS (COP Rate Select)
The COPRS signal reflects the state of the COP rate select bit (COPRS) in the CONFIG1 register.
COPRS — COP Rate Select Bit
COPD — COP Disable Bit
19.4 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.
19.5 Interrupts
The COP does not generate CPU interrupt requests.
19.6 Monitor Mode
When monitor mode is entered with V
on the IRQ1 pin or the RST pin. When monitor mode is entered by having blank reset vectors and not
having V
19.7 Low-Power Modes
The WAIT and STOP instructions put the MCU in low power-consumption standby modes.
Freescale Semiconductor
COPRS selects the COP time out period. Reset clears COPRS.
COPD disables the COP module.
1 = COP time out period = 2
0 = COP time out period = 2
1 = COP module disabled
0 = COP module enabled
TST
on the IRQ1 pin, the COP is automatically disabled until a POR occurs.
