- Built-in Step-up / Step-down circuit
(6) Melody/Buzzer
- Melody function Octave : 3 octaves
Time of musical note : specified by program
- Buzzer output
(7) Base timer
- 15-bit base timer for timekeeping
(8) HALT release
- Five vec t ors
1. 15-bit base timer (500ms overflow output)
2. 15-bit base timer (output every 32ms)
3. S-port
4. P1-port

(9) Stand-by mode
- HALT mode
The program operation will be stopped in this mode. This mode is released by system reset and 5 vectors for HALT
release above-mentioned.
(10) System reset
- RES terminal
- Reset by setting S1 to S4 terminals to “H” level simultaneously.
(11) Oscillation
- 32.768kHz crystal oscillation
- RC oscillation
(12) Power supply
- Ag-battery : VDD1-VSS=1.30V to 1.65V, Step-up voltage (VDD2-VSS=2.4V to 3.3V)
- Li-battery : VDD2-VSS=2.60V to 3.60V, Step-down voltage (VDD1-VSS=1.3V to 1.8V)

Note:
When a Lithium battery has been selected as the power supply, please note the following points.
There are two modes of use for the lithium battery: Backup mode and Normal mode (backup flag off). In backup
mode, the battery potential is applied directly to the oscillation circuit, whereas in Normal mode only half the
battery potential is applied.
Because of the different voltage applied to the oscillation circuit in each mode, there may be a difference in the
generate d o scil lat io n fre quen cy. W hen en ter ing b ac kup mod e a c or re spo ndin g er ro r will a ris e. I f timing acc ura cy
is required (for clocks, etc), please bear in mind the above in the program design.
