Introduction
The General Purpose Timer Unit blocks GPT1 and GPT2 have very flexible multifunctional timer structures which
may be used for timing, event counting, pulse width measurement, pulse generation, frequency multiplication, and
other purposes.
They incorporate five 16-bit timers that are grouped into the two timer blocks GPT1 and GPT2. Each timer in each
block may operate independently in a number of different modes such as Gated timer or Counter Mode, or may
be concatenated with another timer of the same block.
Each block has alternate input/output functions and specific interrupts associated with it. Input signals can be
selected from several sources by register PISEL.
The GPT module is clocked with clock f_GPT. f_GPT is a clock derived from f_SYS.
