1.8.13.11 PIO_PortInterruptDisable Function

C

void PIO_PortInterruptDisable(PIO_PORT port, uint32_t mask)

Summary

Disables IO interrupt on selected IO pins of a port.

Description

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

Precondition

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

Parameters

Param Description
port One of the IO ports from the enum PIO_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 disabled.
  • The bit positions of mask value which are set as 1, IO interrupt of corresponding IO pin of the selected port will be disabled.

  • 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

// Disable IO interrupt for PB9 and PB1 pins
PIO_PortInterruptDisable(PIO_PORT_C, 0x0202);

Remarks

None.
