Figure 3-10 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 I/O lines located at Port 0.
The three timers of GPTU module, T0, T1 and T2, can operate independently of 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
