13.17.8.8 Data Output Value Toggle
The I/O pins are assembled in PORT groups with up to 32 pins. Group 0 consists of the PA pins, group 1 is for the PB pins, etc. Each PORT group has its own set of PORT registers with offset 0x80. The available number of PORT groups may depend on the package/pin number of the device.

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. |
