*SRE <NRf>
The *SRE <NRf> command sets the Service Request Enable register bits.
This register contains a mask value for the bits to be enabled in the Status
Byte Register. A 1 in the Enable Register enables the corresponding bit in
the Status Byte Register; a 0 disables the bit. The parameter value, when
rounded to an integer and expressed in base 2, represents the bits 0 to 5
and bit 7 of the Service Request Enable Register. Bit 6 is always 0.
Table 15-5 shows the contents of this register. Refer to the pullout at the
end of chapter 1 for further information.
