Byte 0: Command
Bit 0: Start zero point adjustment
Bit 1: Freeze process values
Bit 2: Force outputs
Byte 1: Command Validity Mask
Bit coded information to indicate which bit or bits
are valid to be processed by the device.
Bit 0: process

command”
The command bit is only processed if the
corresponding mask bit is set. Otherwise the com-
mand information is ignored.
The concurrent access could happen if an acyclic
master sets up a write request while the cyclic mas-
ter is connected and provides also command data.
The acyclic write request is processed but could be
overwritten by the cyclic master if the validity bit in
scope is set.
