Note:
The products in the Z8 Encore! F0830 Series contain an on-chip crystal oscillator for use
with external crystals with 32 kHz to 20 MHz frequencies. In addition, the oscillator sup-
ports external RC networks with oscillation frequencies up to 4 MHz or ceramic resonators
with frequencies up to 8 MHz. The on-chip crystal oscillator can be used to generate the
primary system clock for the internal eZ8 CPU and the majority of its on-chip peripherals.

The Z8 Encore! F0830 Series products support the following four OSCILLATOR Modes:
The OSCILLATOR Mode is selected using user-programmable Flash option bits. See the
Flash Option Bits
The XTLDIS Flash option bit controls whether the crystal oscillator is enabled during
reset. The crystal may later be disabled after reset if a new oscillator has been selected as
the system clock. If the crystal is manually enabled after reset through the OSCCTL Reg-
