Reading from Device Registers: dalNbcsSswRead
This function can be used to read a register of a specific space switch device by providing the
register number. This function derives the actual address location based on the device handle and
register number inputs. It then reads the contents of this address location
Writing to Device Registers: dalNbcsSswWrite
This function can be used to write to a register of a specific space switch device by providing the
register number. This function derives the actual address location based on the device handle and
register number inputs. It then writes the data to the specified address location.
Reading from a block of Device Registers: dalNbcsSswReadBlock
This function can be used to read a register block of a specific space switch device by providing
the starting register number and the size to read. This function derives the actual start address
location based on the device handle and starting register number inputs. It then reads the contents
of this data block.
