STOPDIS â STOP Instruction Disable Bit
This read-only bit allows emulation of the âSTOP disableâ mask option
on the MC68HC05C12A. (See 5.10 COP During Stop Mode.) If configured in
MC68HC05C9A mode, this bit has no effect and will be forced to 0
regardless of the programmed state.1 = If the MCU enters stop mode, the
clock monitor is enabled to force a system reset0 = STOP instruction
executed as normal C12COPE â C12A COP Enable Bit This read-only bit
enables the COP function when configured in MC68HC05C12A mode. If
configured in MC68HC05C9A mode, this
bit has no effect and will be forced to 0 regardless of the programmed
state.1 = When in C12A mode, this enables the C12ACOP watchdog timer.0 =
When in C12A mode, this disables the C12ACOP watchdog
timer.SEC â Security Enable BitThis read-only bit enables the EPROM
security feature. Onceprogrammed, this bit helps to prevent external
access to the programmed EPROM data. The EPROM data cannot be verified or
modified.
1 = Security enabled
0 = Security disabled
NOTE: During power-on reset, the device always will be configured as
MC68HC05C9A regardless of the state of the C12A bit.
