Features
ADDITIONAL SUPPORT
FLEX System Software from Motorola is a family of software components for building world-
class products incorporating messaging capabilities. FLEXstack™ Roaming Software is
specifically designed to support the Roaming FLEX™ chip IC. FLEXstack Roaming Software
runs on a product’s host processor and takes care of communicating with the FLEX™ chip IC,
acquiring the proper FLEX channel, and fully interpreting the codewords that are passed to the
host from the FLEX™ chip IC.
