2. A 1.8-V external oscillator can be directly connected to the X1 pin. The X2 pin should be left
unconnected and the XCLKIN pin tied low. The logic-high level in this case should not exceed V

TI recommends that customers have the resonator/crystal vendor characterize the operation of their
device with the DSP chip. The resonator/crystal vendor has the equipment and expertise to tune the tank
circuit. The vendor can also advise the customer regarding the proper tank component values that will
produce proper start up and stability over the entire operating range.
3.6.1.2
PLL-Based Clock Module
The 280x devices have an on-chip, PLL-based clock module. This module provides all the necessary
clocking signals for the device, as well as control for low-power mode entry. The PLL has a 4-bit ratio
control PLLCR[DIV] to select different CPU clock rates. The watchdog module should be disabled before
writing to the PLLCR register. It can be re-enabled (if need be) after the PLL module has stabilized, which
takes 131072 OSCCLK cycles.
