Configuration Register (CONFIG)
LVI5OR3 — LVI 5-V or 3-V Operating Mode Bit
SSREC — Short Stop Recovery Bit
STOP — STOP Instruction Enable Bit
COPD — COP Disable Bit
94
LVI5OR3 selects the voltage operating mode of the LVI module (see
(LVI)). The voltage mode selected for the LVI should match the operating V
Electrical
SSREC enables the CPU to exit stop mode with a delay of 32 CGMXCLK cycles instead of a
4096-CGMXCLK cycle delay.
The short stop recovery delay can be enabled when using a crystal or resonator and the
OSCENINSTOP bit is set. The short stop recovery delay can be enabled when an external oscillator
is used, regardless of the OSCENINSTOP setting.
The short stop recovery delay must be disabled when the OSCENINSTOP bit is clear and a crystal or
resonator is used.
STOP enables the STOP instruction.
COPD disables the COP module. See
1 = LVI operates in 5-V mode
0 = LVI operates in 3-V mode
1 = Stop mode recovery after 32 CGMXCLK cycles
0 = Stop mode recovery after 4096 CGMXCLK cycles
1 = STOP instruction enabled
0 = STOP instruction treated as illegal opcode
1 = COP module disabled
0 = COP module enabled
Specifications) for the LVI’s voltage trip points for each of the modes.
The LVI5OR3 bit is cleared by a power-on reset (POR) only. Other resets
will leave this bit unaffected.
Exiting stop mode by any reset will result in the long stop recovery.
