NOTE:
Address:
Reset:
SSREC — Short Stop Recovery Bit
Exiting stop mode by pulling reset will result in the long stop recovery.
If using an external crystal oscillator, do not set the SSREC bit.
COPRS — COP Rate Select Bit
STOP — STOP Instruction Enable Bit
COPD — COP Disable Bit
Read:
Write:
SSREC enables the CPU to exit stop mode with a delay of 32
OSCXCLK cycles instead of a 4096 OSCXCLK cycle delay.
COPRS selects the COP timeout period. Reset clears COPRS. (See
Section 22. Computer Operating Properly
STOP enables the STOP instruction.
COPD disables the COP module. (See
Operating Properly
1 = Stop mode recovery after 32 OSCXCLK cycles
0 = Stop mode recovery after 4096 OSCXCLK cycles
1 = COP timeout period = 2
0 = COP timeout period = 2
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
1 = COP module disabled
0 = COP module enabled
