Questions and Answers
Question 5:Is it possible to configure a power switching circuit containing a diode
Question 6:To what test modes can the TSTA and TSTB bits be applied as test bits
Question 7:What are the possible causes of any changes which may occur to internal time data
Question 8:What are the ranges of operating voltages
RP/RF/RS5C62

Answer 6:The TSTA and TSTB bits are intended for IC selection and not for general users. (These test
bits should be kept at “1” in normal operation and will automatically be set to “1” upon driving
low the CE pin.)
Answer 5:It is not recommendable to configure a power switch-
ing circuit containing a diode, which causes a voltage
drop as shown in the right circuit diagram (where
“D
1
” represents a diode). (The maximum absolute
ratings of the input and output pins range from –0.3V
to the V
DD
plus 0.3V.)

Answer 7:The possible causes of such changes include :
1. Occurrence of writing errors due to such factors as noises caused below the operating volt-
age of the CPU at the time of switching from the power supply to the backup battery,
2. Occurrence of instantaneous power disconnection, and
3. Writing to other addresses than are allocated originally due to shortage of addressing time
(
t
AS
).
To cope with the cause 1. , see “2. Handling of CE Pin” in “USAGE”. To solve the cause 2. ,
check the power supply system to prevent instantaneous power disconnection from occur-
ring. To overcome the cause 3. , secure sufficient addressing time (
t
AS
).
Answer 8:Range of operating voltage of crystal oscillators only for time count operation: 2.0V to 6.0V.
Range of operating voltage having any access to the CPU : 2.7V to 6.0V
Incidentally, AC timing is available in three ratings : 3V±10%, 5V±10%, and 5V±20%.
