2-2-3. Operating of sample application circuit – (2)
(a) At the time of power-ON reset
The operation and notes are the same as for sample application circuit – (1), except that after reset release P
XX
="L" is
program-detected to decide program start after initial reset.
(b) Standby initiation
When one polling regrds the P
XX
input voltage as "L" level, the HALT mode is entered.
(c) At the time of return from power failure backup
After power is restored, a reset occurs, releasing the standby mode.
After standby release P
XX
="H" is program-detected, deciding program start after power is restored.
– Note –
If power is restored after V
DD
during power failure backup gets lower than V
IH
on the P
XX
, P
XX
="L" may be program-
detected, deciding program start after initial reset.
2-2-4. Notes for design of sample application circuit – (2)
R2 and R3
Fix the R2 value so that R2 R1 is yielded and fix the R3 value so that I
B
of TR2 is limited.
R4
There is no severe restriction on the R4 value, but fix it so that C2 can discharge quickly.
Other notes are the same as for sample application circuit – (1).
2-2-5. Notes for software design
Design the program so that port A
3
is brought to "H" level at the standby mode.
Check a standby request by polling the input port once.
