The system can quit the HALT mode by an ex-
ternal reset, an interrupt, an external falling
edge signal on port A or an RTC time out.
The HT9580 has one internal 8-bit D/A con-
verter which can measure the battery voltage
and the RSSI input signal from the IF of the RF
circuit. The DA0~DA7 is the digital input of the
D/Aconverter and the analog outputs to the pin
named DA_OUT. Bit BAT of the DA-H register
(0030H) is the output of the comparator. Its in-
put at the - terminal is from the D/A output
and the + terminal comes from the input pin
BAF. The bit RSSI of DA-H register (0030H) is
the output of another comparator. Its input at
- terminal is from the D/A output and
minal comes from the input pin RSSI. The soft-
ware can detect the battery voltage and the
RSSI signal by writing to the bits DA0 ~DA7
(002FH)andreadingthebitsBAT,RSSI(0030H).
ter-
Bit D/A_PD is used for the D/A power down
control.Ifthisbitislogichigh,theD/Awillbein
the power down mode. Otherwise, the D/A is in
the normal condition. For details see the follow-
ing figure.
