6.11 *SRE
<
NRf
>
The
*SRE
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 Register, a
0
disables the corresponding bit in the Status Register. The parameter value
when expressed in base 2, represents bits 0 to 5 and bit 7 of the Service Request Enable Register. Bit 6
is not used and is always
0
. Table 4.11 shows the contents of this register.
