Configuring ISR Processing: suni4x622ISRConfig
Allows the USER to configure how ISR processing is to be handled: polling
(
SUNI4x622_POLL_MODE) or interrupt driven (SUNI4x622_ISR_MODE). If polling is selected,
the USER is responsible for calling periodically
suni4x622Poll to collect exception data from
the device.
Prototype
INT4 suni4x622ISRConfig(sSUNI4x622_HNDL deviceHandle,
eSUNI4x622_ISR_MODE mode)
Inputs
deviceHandle : device handle (from suni4x622Add)
mode : mode of operation
Outputs
None
Returns
Success =
SUNI4x622_SUCCESS
Failure = SUNI4x622_ERR_INVALID_DEVICE_STATE
SUNI4x622_ERR_INVALID_DEV
SUNI4x622_ERR_INVALID_ARG
Valid States
SUNI4x622_ACTIVE, SUNI4x622_INACTIVE
Side Effects
None
Getting Device Interrupt Enable Mask: suni4x622GetMask
This function returns the contents of the interrupt mask registers of the S/UNI-4x622 device.
Prototype
INT4 suni4x622GetMask(sSUNI4x622_HNDL deviceHandle,
sSUNI4x622_MASK_ISR *pmask)
Inputs
deviceHandle : device handle (from suni4x622Add)
pmask : (pointer to) mask structure
Outputs
pmask : (pointer to) updated mask structure
Returns
Success =
SUNI4x622_SUCCESS
Failure = SUNI4x622_ERR_INVALID_DEVICE_STATE
SUNI4x622_ERR_INVALID_DEV
SUNI4x622_ERR_INVALID_ARG
Valid States
SUNI4x622_ACTIVE, SUNI4x622_INACTIVE
Side Effects
None
Setting Device Interrupt Enable Mask: suni4x622SetMask
This function sets the contents of the 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.
