Bit #
Name
Default
Bits 0 to 2/Address ESI3 Data Output Select (ESI3SEL0 to ESI3SEL2). These bits select what status is to be output when
the device decodes an ESI3 address during a bus read operation.
Bit 3/Unused, must be set to zero for proper operation.
Bits 4 to 6/Address ESI4 Data Output Select (ESI4SEL0 to ESI4SEL2). These bits select what status is to be output when
the device decodes an ESI4 address during a bus-read operation.
