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.
