Setting LO H Interrupt Enable Mask: suni4x 622Se tMaskLOH

This function sets the contents of the LOH 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 suni4x622SetMaskLOH(sSUNI4x622_HNDL
deviceHandle, UINT1 channel, sSUNI4x622_MASK_ISR
*pmask)
Inputs deviceHandle : device handle (from suni4x622Add)
channel : channel number
pmask : (pointer to) mask structure
