Semantics The Service Request "Enable" Register consists of 8 bits: Bit0 to Bit7. Bit6 is not

defined, and is always 0. The Service Request "Enable" Register determines which

bits of the Status Byte Register are enabled.

The status of the enabled bits are ORed together, and the result of OR is output to

bit6 (Master Summary Status bit) of Status Byte Register. For details, refer to

“Status Reporting Structure” on page 7-48.

The following table shows the bits of the Status Byte Register, and the

binary-weighted decimal value of each bit.
