Oscillator configuration
The HT84XXX series provides an RC oscillator
for the system clock. The system oscillator
stops in the standby state so as to reduce power
consumption.
For the oscillator circuit, an external resistor is
required between OSC and VSS. The oscillator
frequency is typically 4MHz for an external re-
sistor of 240k . The RC type of oscillator offers
the most cost-effective solution, although the
frequency of the oscillation may vary with tem-
perature and the chip itself due to process vari-
ation.
