OUT

Data Output Value

Important: For SAM L11 Non-Secure accesses, read and write accesses (RW*) are allowed only if the security attribution for the corresponding I/O pin is set as Non-Secured in the NONSEC register.

This register sets the data output drive value for the individual I/O pins in the PORT.

This register can be manipulated without doing a read-modify-write operation by using the Data Output Value Clear (OUTCLR), Data Output Value Set (OUTSET), and Data Output Value Toggle (OUTTGL) registers.

Tip: The I/O pins are assembled in pin groups (”PORT groups”) with up to 32 pins. Group 0 consists of the PA pins, group 1 is for the PB pins, etc. Each pin group has its own PORT registers, with a 0x80 address spacing. For example, the register address offset for the Data Direction (DIR) register for group 0 (PA00 to PA31) is 0x00, and the register address offset for the DIR register for group 1 (PB00 to PB31) is 0x80.

Bits 31:0 – OUT[31:0]: PORT Data Output Value

PORT Data Output Value

For pins configured as outputs via the Data Direction register (DIR), these bits set the logical output drive level.

For pins configured as inputs via the Data Direction register (DIR) and with pull enabled via the Pull Enable bit in the Pin Configuration register (PINCFG.PULLEN), these bits will set the input pull direction.

ValueDescription
0 The I/O pin output is driven low, or the input is connected to an internal pull-down.
1 The I/O pin output is driven high, or the input is connected to an internal pull-up.
