2.5.2
Service Request Enable (SRE)
The SRE is used to control the status line when Status-Monitors-
Overload Mode is disabled (See
STOL
).
This is an 8-bit wide register. Each bit in the SRE corresponds one-to-
one with a bit in the SB register, and acts as a bitwise AND of the SB
flags. If any bits are simultaneously set in both the SB and the SRE,
then a service request is indicated and the
−
STATUS signal (pin 2 on
the Dsub-15 SIM Interface Connector) is asserted low.
This register is set and queried with the
*SRE(?)
command. On
Power-On, this register is cleared.
