PROGRAM EXAMPLE: BURST–MODE DATA LOGGER
;***************************************************************************
;Program DATA_LOG
;
;This program demonstrates burst mode operation in a data logger device. The
;device remains in Stop mode until a real time clock or external interrupt
;resumes operation. When an operation is complete, the device will switch
;back to the ring oscillator and return to Stop mode.
;
;The real time clock will interrupt the system twice per hour to read a value
;from port 1, which it will store until requested. The interrupt is called
;on the hour to start the data acquisition. The routine presented is simple and
;generic, so the data could be from a D/A converter or a temperature sensor,
;for example.
;
;Upon receiving an external interrupt, the device will start the crystal
;amplifier in expectation of possible serial port activity, but continue to
;operate from the ring oscillator. If serial activity is detected or desired,
;the device will hold operation until the crystal has warmed up, and then
;switch operation to it.
