TC11IB
The three timers in each GPTU Module T0, T1, and T2, can operate independently from
each other or can be combined:
General Features:
• All timers are 32-bit precision timers with a maximum input frequency of f_GPTU.
• Events generated in T0 or T1 can be used to trigger actions in T2
• Timer overflow or underflow in T2 can be used to clock either T0 or T1
• T0 and T1 can be concatenated to form one 64-bit timer
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 determine 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.
