• Description: S12 Microcontrollers Mcu 16-bit Hcs12 Cisc 32kb Flash 5v Tray
• Manufacturer: Freescale Semiconductor, Inc

Windowed COP operation is enabled by setting WCOP in the CPMUCOP register. In this mode, writes to
the CPMUARMCOP register to clear the COP timer must occur in the last 25% of the selected time-out
period. A premature write will immediately reset the part.
7.5.3
The on-chip POR circuitry detects when the internal supply V
(voltage level not specified in this document because this supply is not visible on device pins). POR is
deasserted, if the internal supply V
this document because this supply is not visible on device pins).
7.5.4
The on-chip LVR circuitry detects when one of the supply voltages V
appropriate voltage level. If LVR is deasserted the MCU is fully operational at the specified maximum
speed.The LVR assert and deassert levels for the supply voltage VDDX are V
specified in the device Reference Manual.
7.6
The interrupt/reset vectors requested by the S12CPMU are listed in
specification for related vector addresses and priorities.
