Preliminary

Timer Units

The TC1765 includes two timer units:

– General Purpose Timer Unit (GPTU)

– General Purpose Timer Array (GPTA)

General Purpose Timer Unit

Figure 8 shows a global view of the General Purpose Timer Unit (GPTU) module.

General Block Diagram of the GPTU Interface

The GPTU consists of three 32-bit timers designed to solve such application tasks as

event timing, event counting, and event recording. The GPTU communicates with the

external world via eight inputs and eight outputs located at Port 0.

The I/O has three timers (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

fGPTU.

• 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.
