Configuration Register (CONFIG)
MSCANEN— MSCAN08 Enable Bit
TMCLKSEL— Timebase Clock Select Bit
OSCENINSTOP — Oscillator Enable In Stop Mode Bit
ESCIBDSRC — SCI Baud Rate Clock Source Bit
COPRS — COP Rate Select Bit

Setting the MSCANEN enables the MSCAN08 module and allows the MSCAN08 to use the PTC0/PTC1
pins. See
MSCAN08 operation.
TMCLKSEL enables an extra divide-by-128 prescaler in the timebase module. Setting this bit enables
the extra prescaler and clearing this bit disables it. See
a more detailed description of the external clock operation.
OSCENINSTOP, when set, will enable the oscillator to continue to generate clocks in stop mode. See
Chapter 4 Clock Generator Module
the reset of the MCU stops. See
to generate clocks while in stop mode. The default state for this option is clear, disabling the oscillator
in stop mode.
ESCIBDSRC controls the clock source used for the serial communications interface (SCI). The setting
of this bit affects the frequency at which the SCI operates.See
Communications Interface (ESCI)
COPD selects the COP timeout period. Reset clears COPRS. See
Properly (COP) Module
1 = Enables MSCAN08 module
0 = Disables the MSCAN08 module
1 = Enables extra divide-by-128 prescaler in timebase module
0 = Disables extra divide-by-128 prescaler in timebase module
1 = Oscillator enabled to operate during stop mode
0 = Oscillator disabled during stop mode (default)
1 = Internal data bus clock used as clock source for SCI (default)
0 = External oscillator used as clock source for SCI
1 = COP timeout period = 2
0 = COP timeout period = 2
Note: LVI5OR3 bit is only reset via POR (power-on reset).

The MSCANEN bit is cleared by a power-on reset (POR) only. Other resets
will leave this bit unaffected.
