Configuration Register (CONFIG)
Advance Information
50
NOTE:
NOTE:
Address:
The CONFIG register is a special register containing one-time writable
latches after each reset. Upon a reset, the CONFIG register defaults to
the predetermined settings as shown in
SSREC — Short stop recovery bit
Exiting stop mode by pulling reset will result in the long stop recovery.
If using an external crystal, do not set the SSREC bit.
COPRS — COP reset period selection bit
STOP — STOP instruction enable bit
COPD — COP disable bit
Reset:
Read:
Write:
SSREC enables the CPU to exit stop mode with a delay of 32
CGMXCLK cycles instead of a 4096 CGMXCLK cycle delay.
STOP enables the STOP instruction.
COPD disables the COP module.
Operating Properly
1 = Stop mode recovery after 32 CGMXCLK cycles
0 = Stop mode recovery after 4096 CGMXCLK cycles
1 = COP reset cycle is (2
0 = COP reset cycle is (2
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
1 = COP module disabled
0 = COP module enabled
