Description The INHOUSE:REGINT command controls the module’s response type to an interrupt

acknowledge cycle.

When REGINT is set to false, the module uses reqt/reqf (request true/request false),

provided the latched interrupt bit is set tin the ‘SRE’. A reqt (upper 8 bits are 0x7D) is

generated for every latched event and a reqf (upper 8 bits are 0x7C) is generated for

every reading of the latched information using either pseudo register access or word

serial FETch:LATChed? Command.

When REGINT is set to true, only one interrupt is generated every time a latching

occurs. The upper 8 bits of the 16-bit SRE register on (0x7B).

Note: All letters of the command are required; there is no short form of the command.

Examples Command / Query Response (Description)

INHOUSE:REGINT 1 (Sets REGINT to true)

INHOUSE:REGINT? 1 (Indicates that REGINT is set to true)

Related Commands INHOUSE:REG_ENABLE

INHOUSE:PSEUDO
