4.3.4 Chip Select Registers
The following paragraphs provide descriptions of the registers in the chip select function,
and an example of how to program the registers. The chip select registers cannot be used
until the V-bit in the MBAR is set.
MOTOROLA
1 = A loss of input signal reference has been detected, and the VCO is running at
0 = External input signal frequency is at VCO reference.
1 = VCO has locked onto the desired frequency (or system clock is driven
0 = VCO is enabled, but has not yet locked.
1 = Loss of input signal causes a system reset.
0 = Loss of input signal causes the VCO to operate at a nominal speed without
1 = When LPSTOP is executed, the SIM40 clock is driven from the VCO.
0 = When LPSTOP is executed, the SIM40 clock is driven from an external crystal or
1 = When the LPSTOP instruction is executed, the external clock pin (CLKOUT) is
0 = When the LPSTOP instruction is executed, the external clock (CLKOUT) is held
