/*
 * Code Configuration Section
 *
 * The TLG API supports two modes of operation for multi-version chip support.
 * 1) Runtime chip support
 *      With this option all code for all versions of the chip is compiled
 *      into the TLG API and runtime checks are made to determine which code
 *      is to be executed based on chip version. This mode is enabled by
 *      the #define TLG_SUPPORT_RUNTIME_CHECK statement.
 *
 * 2) Compile-time chip support
 *      With this option only the code for the currently defined chip version
 *      (see TLG_CHIP_TYPE and TLG_CHIP_REV) is compiled into TLG API. This
 *      mode is enabled by NOT adding the TLG_SUPPORT_RUNTIME_CHECK statement.
 *
 * By default the TLG API is setup to support the Runtime chip support mode.
 * This is good for early development and while transitioning from one version
 * of chip to another. However, there is a small execution and codespace
 * savings for using the Compile-time mode, so this can be used for 
 * the production version of code if desired.
 */
/** Support Runtime determination of which chip to support.
* Remove this define to enable compile-time chip support.
