20 MHz Primary Crystal Oscillator Operation
The eZ80L92 MCU features two on-chip oscillators for use with an external crystal.
The primary oscillator generates the system clock for the internal CPU and for the major-
ity of the on-chip peripherals. Alternatively, the X
clock input signal. If an external clock generator is used, the X
disconnected. The secondary oscillator can drive a 32 kHz crystal to generate the
time-base for the real time clock.
