HD404829R Datasheet, PDF (99/149 Pages) Renesas Technology Corp – AS Microcomputer Incorporating a LCD controller/Driver Circuit
HD404829R Series
Note on Use: Use the SEM and SEMD instructions to write data to the A/D start flag (ADSF: $020, bit 2),
but make sure that the A/D start flag is not written to during A/D conversion. Data read from the A/D data
register (ADRL: $017, ADRU: $018) during A/D conversion cannot be guaranteed.
The A/D converter does not operate in the stop, watch, and subactive modes because of the OSC clock.
During these low-power dissipation modes, current through the resistor ladder is cut off to decrease the
power input.
