5.5.3.1Usage Hints

1)Read bit 7 of CRD at each system power-up to vali- date the contents of the RTC registers and the CMOS RAM. When this bit is 0, the contents of these regis- ters and the CMOS RAM are questionable. This bit is reset when the backup battery voltage is too low. The voltage level at which this bit is reset is below the mini- mum recommended battery voltage, 2.4V. Although the RTC oscillator may function properly and the regis- ter contents may be correct at lower than 2.4V, this bit is reset since correct functionality cannot be guaran- teed. System BIOS may use a checksum method to revalidate the contents of the CMOS-RAM. The check- sum byte should be stored in the same CMOS RAM.

2)Change the backup battery while normal operating power is present, and not in backup mode, to maintain valid time and register information. If a low leakage

capacitor is connected to VBAT, the battery may be changed in backup mode.

3)A rechargeable NiCd battery may be used instead of a non-rechargeable Lithium battery. This is a preferred solution for portable systems, where small size com- ponents is essential.

4)A supercap capacitor may be used instead of the nor- mal Lithium battery. In a portable system usually the

VSB voltage is always present since the power man- agement stops the system before its voltage falls to low. The supercap capacitor in the range of 0.047- 0.47 F should supply the power during the battery replacement.
