Subject: asynMask in asynDriver

Hi,
   How to possible pass mask with asynInt32 interface?
I am using asynInt32 interface for mbbi record. 
As explain in asynDriver manaul,   we can use 
    
    field(INP,"@asyn(portName,addr,timeout) drvParams")
     or
    field(INP,"@asynMask(portName,addr,nbits,timeout) drvParams")

for asynInt32 device support.

But when i am using " asynMask"  for INP  it gives an error " devAsynInt32 process read error invalid INST_IO Must be asyn(<port> <addr> <timeout>)userParams " on the IOC shell.

Is it possible to use field(INP,"@asynMask(portName,addr,nbits,timeout) drvParams") with DTYP=asynIn32 or i have to use asynUInt32 only?

Thanks
Vikram
