DIGITAL CELLULAR PHONE HAVING A CDMA MODEM CHIPSET AND METHOD FOR CONTROLLING THE CHIPSET

摘要

The present invention relates to a digital portable telephone having a code division multiple access modem chipset implemented as a digital signal processor and a method of driving the chipset in a host of the telephone, which facilitates a communication interface with a host.;The host of the digital portable telephone sends a search command to the digital signal processing unit of the code division multiple access modem chipset, and in response, receives the search result and finger information transmitted from the digital signal processing unit in the form of a message. As a result of analyzing one search result and finger information, if a finger needs to be changed, a finger assignment command is sent to the digital signal processor. The code division multiple access modem chipset has an interface control unit for communication between the digital signal processing unit and the host.
