Setting FIFO Interrupt Enable Mask: suni4x622SetMaskFIFO
This function sets the contents of the FIFO interrupt mask registers of the S/UNI-4x622 device.
Any bits that are set in the passed structure are set in the associated S/UNI-4x622 registers.
Prototype
INT4 suni4x622SetMaskFIFO(sSUNI4x622_HNDL
deviceHandle, UINT1 channel, sSUNI4x622_MASK_ISR
*pmask)
Inputs
deviceHandle : device handle (from suni4x622Add)
channel : channel number
pmask : (pointer to) mask structure
Outputs
None
Returns
Success =
SUNI4x622_SUCCESS
Failure = SUNI4x622_ERR_INVALID_DEVICE_STATE
SUNI4x622_ERR_INVALID_DEV
SUNI4x622_ERR_INVALID_CHAN
SUNI4x622_ERR_INVALID_ARG
Valid States
SUNI4x622_ACTIVE, SUNI4x622_INACTIVE
Side Effects
May change the operation of the ISR / DPR
Clearing FIFO Interrupt Enable Mask: suni4x622ClrMaskFIFO
This function clears FIFO individual interrupt bits and registers in the S/UNI-4x622 device. Any
bits that are set in the passed structure are cleared in the associated S/UNI-4x622 registers.
Prototype
INT4 suni4x622ClrMaskFIFO(sSUNI4x622_HNDL
deviceHandle, UINT1 channel, sSUNI4x622_MASK_ISR
*pmask)
Inputs
deviceHandle : device handle (from suni4x622Add)
channel : channel number
pmask : (pointer to) mask structure
