Abstract
A digital microprocessor device (2) has: a central processing unit; a memory (8); and an output signal module (4). The output signal module comprises: a counter (6) arranged to count to a predetermined count value; and at least one comparator (10a, 10b, 10c) arranged to change an output signal (14a, 14b, 14c) from a first output state to a second output state when the counter reaches a predetermined comparator value. The output signal module is arranged to load automatically from the memory at least one parameter selected from the group comprising: the predetermined count value, the predetermined comparator value and the first output state or the second output state, without receipt of an instruction from the central processing unit.
Claims13
A digital microprocessor device having:
- a central processing unit;
- a memory;
- and
- an output signal module, arranged to operate without using the central processing unit, the output signal module comprising:
- a counter arranged to count to a predetermined count value;
- and
- at least one comparator arranged to change an output signal from a first output state to a second output state when said counter reaches a predetermined comparator value;
- wherein said device has an operating cycle wherein the period of said operating cycle comprises a time between successive instances of the counter reaching the predetermined count value,
- wherein said output signal module is arranged to load automatically from said memory said predetermined count value without receipt of an instruction from said central processing unit;
- the device being arranged such that the predetermined count value can be changed in every cycle.
