Preliminary data sheet
10.1.2 timestamping
10.1.3 event sequence monitoring and signal generation
10.1.4 GPIO pin reset value
Note that this capability is useful for low/medium speed software implemented
protocols, as well as for observing switches, driving LEDs etc. It is highly
recommended to first use the powerful GPIO pins as protocol emulators, and not just
for static switches/LEDs (for which a solution such as a PCF8574 I
fine).
The GPIO module contains 12 timestamp units, each of which can be designated to
monitor an external GPIO pin or internal system event. For a monitored event, a
timestamp unit can be set to trigger on a rising edge, falling edge or either edge.
When a trigger occurs, a precise occurrence time (31-bit timestamp value, 75 ns
resolution) is put in a register, and an interrupt is generated.
This capability is particularly valuable for precise monitoring of key audio/video events
and controlling the internal software phase-locked loops that lock to broadcast time
references. It can also be used for medium speed signal analysis.
GPIO contains 4 queue units, each capable of monitoring or generating high-speed
signals on up to 4 GPIO pins.
This capability creates a universal protocol emulator, capable of emulating many
medium speed (0 - 20 Mbit/s) protocols using software on the TM5250 media
processor. Complex protocols, such as the MemoryStick
peak rate and 800 KB/s sustained file transfer rate have been successfully
implemented on the PNX8525 GPIO module. The PNX17xx Series GPIO is similar to
the PNX8525 GPIO module.
High speed signal analysis uses one of two modes:
Signal generation uses the same 2 features, but in reverse, i.e. a sampled signal is
transmitted, or an in-memory timestamped list of change events is output over a pin.
The event sequence monitoring mechanism can be used for many functions, and is
particularly useful for interpreting Remote Control commands, as described in
Section
The GPIO module has a total of 4 complex signal analysis/signal synthesis resources
capable of sampling or timestamped list generation/creation.
Dedicated GPIO pins come in two types:
•
•
event queue hardware samples 1, 2 or 4 GPIO inputs using one out of a variety of
clocks in the system, including clock inputs or clocks generated from other GPIO
pins. Samples are packed in a word and stored in a list in system memory for
software analysis.
event queue hardware builds an in-system memory list of timestamped GPIO pin
change events, individual per monitored GPIO pin. Edge events are timestamped
with 75 ns resolution.
10.2. Signal generation is useful for RC Blaster applications.
