32.8.7 Data Output Value Set
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 allows the user to set one or more output I/O pin drive levels high, without doing a read-modify-write operation. Changes in this register will also be reflected in the Data Output Value (OUT), Data Output Value Toggle (OUTTGL) and Data Output Value Clear (OUTCLR) 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 – OUTSET[31:0] PORT Data Output Value Set
Writing '0' to a bit has no effect.
Writing '1' to a bit will set the corresponding bit in the OUT register, which sets the output drive level high for I/O pins configured as outputs via the Data Direction register (DIR). For pins configured as inputs via Data Direction register (DIR) with pull enabled via the Pull Enable register (PULLEN), these bits will set the input pull direction to an internal pull-up.| Value | Description |
|---|---|
| 0 | The corresponding I/O pin in the group will keep its configuration. |
| 1 | The corresponding I/O pin output is driven high, or the input is connected to an internal pull-up. |
