Table 34-3. GPIO interface-detailed signal descriptions
Signal
I/O
Description
Deassertion: When output,
this signal occurs on the
rising-edge of the system
clock. For input, it may occur
at any time and input may be
asserted asynchronously to
the system clock.
NOTE
Not all pins within each port are implemented on each device.
See the chapter on signal multiplexing for the number of GPIO
ports available in the device.
34.2 Memory map and register definition
Any read or write access to the GPIO memory space that is outside the valid memory
map results in a bus error.
NOTE
For simplicity, each GPIO port's registers appear with the same
width of 32 bits, corresponding to 32 pins. The actual number
of pins per port (and therefore the number of usable control bits
per port register) is chip-specific. Refer to the Chip
Configuration chapter to see the exact control bits for the non-
identical port instance.
