20 MHz Primary Crystal Oscillator Operation
The eZ80F92 device features two on-chip oscillators for use with an external crystal. The
primary oscillator generates the system clock for the internal CPU and the majority of the
on-chip peripherals. Alternatively, the X
input signal. If an external clock generator is used, the X
The secondary oscillator can drive a 32 kHz crystal to generate the time-base for the Real-
Time Clock.
