TC1796
Functional Description
3.14
General Purpose Timer Array
The GPTA provides a set of timer, compare and capture functionalities that can be
flexibly combined to form signal measurement and signal generation units. They are
optimized for tasks typical of engine, gearbox, and electrical motor control applications,
but can also be used to generate simple and complex signal waveforms needed in other
industrial applications.
The TC1796 contains two General Purpose Timer Arrays (GPTA0 and GPTA1) with
identical functionality, plus an additional Local Timer Cell Array (LTCA2). Figure 14
shows a global view of the GPTA modules.
