Register Description:
Register Address:
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 DS2155 decodes an ESI3 address during a bus read operation.
Bit 3/Unused, must be set to 0 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 DS2155 decodes an ESI4 address during a bus read operation.
Bit 7/Unused, must be set to 0 for proper operation
