ABSTRACT:
A time slot assigner (20) for a serial communication system utilizes an encoded field of data. The time slot assigner (20) has a memory (52) for storing encoded data, a digital counter (60), a prescaler (62), a dedicated latch (58), and a time slot control logic (56). The enclosed data is partitioned into encoded data fields within the memory. A first encoded data field is utilized to indicate a last (LST) encoded data entry of a plurality of entries in the memory to be processed collectively, a second encoded data field (BRS) indicates a bit resolution of the data, a third encoded data field contains a count (CNT) value, and a fourth encoded data field selects a serial communication channel (CSEL). The time slot assigner (20) is activated by an active strobe start cycle signal, and is deactivated in response to a predetermined activated encoded data field.
