The Service Request Enable Register is used to individually
enable bits in the Status Byte to set the MSS bit of the Status Byte,
thereby generating an interrupt. When the bit of the Service
Request Enable bit is set, and the corresponding bit of the Status
Byte Register is set, then the MSS bit will be a 1.
