Note: The LC89210 nominal external clock frequency is 29.4912 MHz. This value has a precision of ±5.10–5.

Boundary Scan Interface

The LC89210 provides 13 signals for testing. These signals can be used along with the SGS-Thomson ST18932

boundary scan development tools in the product development process to debug application hardware and software. If this

function is not used, all of these input signal must be connected to ground, and all of these output signals must be left

open.
