add 'togglePin' convenience function (#8734)
* add 'togglePin' conveniance function
for AVR and chibios
* drop outmost parantheses
Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com>
* toggle pin on avrs
toggle a pin configured as output by writing the corresponding bit to the PIN register
Co-Authored-By: Takeshi ISHII <2170248+mtei@users.noreply.github.com>
* togglepin: add documentation for newly added function
* Update docs/internals_gpio_control.md
Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com>
* on AVR: use PORTD to toggle the output
... since not all MCUs support toggling through writing to PIN
