Abstract
A radio (10) executes a method (100) for entering and exiting a halt status. Radio (10) has a control unit (18) and an internal timing unit (16). The timing unit (16) has execution logic (32), a status register (46) a counter (30) and a clock source (37). The control unit (18) writes instructions I(i) and their execution times T(i) to a memory (42) within the execution logic (32). One of these instructions is a `SWITCH CLOCK` instruction causing the timing unit (16) to switch between clock signals. One of the instructions is `HALT COUNTER` causing the radio (10) to enter a halt state. The radio (10) can be synchronized to the end of a first communication frame received by it after exiting a halt state.
