FUNCTION

R In D/C controlled power down state, crystal

oscillator stays running.

In D/C controlled power down state, crystal

oscillator stops.

R Oscillator in normal power, high accuracy, mode.

Oscillator in low power, medium accuracy mode.

R If crystal is used, enable clock output driver

If crystal is used, disable clock output driver (Hi-Z)

R Normal operation

Causes a software reset, which forces all registers

into their reset state. If ECHO is true, then the echo

will occur at the current baud rate, before the baud

rate changes to the default value.
