C
void GPIO_PortToggle(GPIO_PORT port, uint32_t mask)
Summary
Toggles the selected IO pins of a port.
Description
This function toggles (or invert) the selected IO pins of a port.
Precondition
Pins of the port must be made output before toggling.
Parameters
| Param | Description |
|---|---|
| port | One of the IO ports from the enum GPIO_PORT |
| mask | A 32 bit value in which positions of 0s and 1s decide which IO pins of the selected port will be toggled. |
-
1's Will toggle (invert) corresponding IO pins.
-
0's Will remain unchanged.
Returns
None.
Example
// Toggles RC5 and RC7 pins GPIO_PortToggle(GPIO_PORT_C, 0x00A0);
Remarks
If the port has less than 32-bits, unimplemented pins will be ignored. Implemented pins are Right aligned in the 32-bit value.
