21.8.7 Data Output Value Set
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.

Bits 31:0 – OUTSET[31:0]: Port Data Output Value Set
0: The I/O pin output is driven low.
0: The I/O pin output is driven low.
1: The I/O pin output is driven high.
Writing a zero to a bit has no effect.
Writing a one 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 the Data Direc-
tion register (DIR) with pull enabled via the Pull Enable register (PULLEN), these bits will set the input pull direction
to an internal pull-up.
