C

void GPIO_PortInterruptEnable(GPIO_PORT port, uint32_t mask)

Summary

Enables IO interrupt on selected IO pins of a port.

Description

This function enables interrupt on selected IO pins of selected port.

Precondition

Corresponding pins must be configured in interrupt mode in MHC Pin Manager. GPIO_Initialize() must have been called.

Parameters

Param Description
port One of the IO ports from the enum GPIO_PORT
mask Is a 32 bit value in which positions of 0s and 1s decide which IO pins of the selected port will have interrupt enabled.
  • The bit positions of mask value which are set as 1, IO interrupt of corresponding IO pin of the selected port will be enabled.

  • The bit positions of mask value which are cleared to 0, IO interrupt of corresponding IO pin of the selected port will remain unchanged.

Returns

None.

Example

// Enable IO interrupt for RC5 and RC7 pins
GPIO_PortInterruptEnable(GPIO_PORT_C, 0x00A0);

Remarks

None.
