Figure 9 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 13.
The three timers of the 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
