I/O Lines Programming Example
SAM9M10
The programing example as shown in
configuration.
Table 30-1.
• 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, no pull-up resistor
• I/O line 24 to 27 assigned to peripheral A with Input Change Interrupt and pull-up resistor
