System Clock Configuration
The MC321x device allows for a wide array of system clock configurations:
Pins are provided for a separate external clock source for the CPU. The external clock source can
by derived from a crystal oscillator or from an external clock source
Pins are provided for a 16 MHz crystal for the modem clock source (required)
The modem crystal oscillator frequency can be trimmed through programming to maintain the tight
tolerances required by IEEE 802.15.4
The modem provides a CLKO programmable frequency clock output that can be used as an
external source to the CPU. As a result, a single crystal system clock solution is possible
Out of reset, the MCU uses an internally generated clock (approximately 8-MHz) for start-up. This
allows recovery from stop or reset without a long crystal start-up delay
The MCU contains an internal clock generator (which can be trimmed) that can be used to run the
MCU for low power operation. This internal reference is approximately 243 kHz
