29.7.8 Data Output Value Toggle
This register allows the user to toggle the drive level of one or more output I/O pins, without doing a read-modify-write operation. Changes in this register will also be reflected in the Data Output Value (OUT), Data Output Value Set (OUTSET) 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 – OUTTGL[31:0] PORT Data Output Value Toggle
Writing '0' to a bit has no effect.
Writing '1' to a bit will toggle the corresponding bit in the OUT register, which inverts the output drive level 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 toggle the input pull direction.Value | Description |
---|---|
0 | The corresponding I/O pin in the PORT group will keep its configuration. |
1 | The corresponding OUT bit value is toggled. |
