SAM9X25
The programing example as shown in
configuration.
Table 23-1.
• 4-bit output port on I/O lines 0 to 3, (should be written in a single write operation), open-drain,
• Four output signals on I/O lines 4 to 7 (to drive LEDs for example), driven high and low, no
• Four input signals on I/O lines 8 to 11 (to read push-button states for example), with pull-up
• Four input signals on I/O line 12 to 15 to read an external device status (polled, thus no input
• I/O lines 16 to 19 assigned to peripheral A functions with pull-up resistor
• I/O lines 20 to 23 assigned to peripheral B functions with pull-down resistor
• I/O line 24 to 27 assigned to peripheral C with Input Change Interrupt, no pull-up resistor and
• I/O line 28 to 31 assigned to peripheral D, no pull-up resistor and no pull-down resistor
with pull-up resistor
pull-up resistor, no pull-down resistor
resistors, glitch filters and input change interrupts
change interrupt), no pull-up resistor, no glitch filter
no pull-down resistor
