Fixed Interval Timer, FIT
The Fixed Interval Timer generates a strobe signal at fixed intervals. The Fixed Interval
Timer asserts the output signal and generates an interrupt according to the selected
parameter values.
Programmable Interval Timer, PIT
The Programmable Interval Timer, PIT, has a configurable width from 1 to 32. The PIT
operation and period are controlled by software. An interrupt can be generated when the
timer lapses.
General Purpose Output, GPO
The General Purpose Output, GPO, drives I/O Module GPO output signals defined by the
value of the corresponding GPO register, programmable from software. The width and
initial value are defined by parameters.
General Purpose Input, GPI
The General Purpose Input, GPI, makes it possible for software to sample the value of the
I/O Module GPI input signals by reading the GPI register. The width and whether to
generate an interrupt are defined by parameters.
Interrupt Controller INTC
The Interrupt Controller handles both I/O module internal interrupt events and external
ones. The internal interrupt events originate from the UART, the Fixed Interval Timers, the
Programmable Interval Timers, or the General Purpose Inputs.
