Abstract:
A radio having a halting apparatus, the radio comprising:a timing unit providing a timing signal within the radio;a control unit coupled to the timing unit;a memory coupled to the control unit, for receiving a series of instructions I(i) from the control unit, the instruction I(i) comprising operand instructions O(i) for controlling operations of the radio and time of execution instructions T(i) specifying when each O(i) is to be executed, where i is an index having values 1 to N;a status register, having a plurality of flags, coupled to the control logic and timing unit, for indicating the status of the timing unit and for saving a control unit request to synchronize timing unit operation;wherein, when the timing unit is stopped, it sets a timing unit status flag within the status register;wherein, the timing unit resets the timing unit status flag following the end of a first communication frame received by radio after the timing unit is started or after the timing unit exits a halt status; andwherein, when the timing unit status flag is set, the timing unit does not execute further instructions within the communication frame.
