Data Sheet

V1.2, 2002-12

Preliminary

Features of T0 and T1:

• Each timer has a dedicated 32-bit reload register with automatic reload on overflow.

• Timers can be split into individual 8-, 16-, or 24-bit timers with individual reload

registers.

• Overflow signals can be selected to generate service requests, pin output signals, and

T2 trigger events.

• Two input pins can define a count option.

Features of T2:

• Count up or down is selectable

• Operating modes:

–Timer

– Counter

– Quadrature counter (incremental/phase encoded counter interface)

• Options:

– External start/stop, one-shot operation, timer clear on external event

– Count direction control through software or an external event

– Two 32-bit reload/capture registers

• Reload modes:

– Reload on overflow or underflow

– Reload on external event: positive transition, negative transition, or both transitions

• Capture modes:

– Capture on external event: positive transition, negative transition, or both

transitions

– Capture and clear timer on external event: positive transition, negative transition, or

both transitions

• Can be split into two 16-bit counter/timers

• Timer count, reload, capture, and trigger functions can be assigned to input pins. T0

and T1 overflow events can also be assigned to these functions.

• Overflow and underflow signals can be used to trigger T0 and/or T1 and to toggle

output pins.

• T2 events are freely assignable to the service request nodes.
