14.3 Control Register Contents (Control System to
Gateway)
14.3.1 General Information
The Control Register is (if enabled) located at 0x200–0x201 and constitutes a bit-field as follows:
Note: Internally, this is treated as a Motorola-format word (i.e. MSB first). If the higher level network
uses a different byte order, the upper and lower bytes will appear to be swapped.
14.3.2 Control Codes in Master Mode and DF1 Master Mode
(This table is valid only in Master Mode and DF1 Master Mode).
14.3.3 Control Codes in Generic Data Mode
(No Control Codes are currently supported in this mode).
bit(s) Name Description
15 Confirm
(CR_HS_CONFIRM)
These bits control the handshaking towards the gateway.

14 Send
(CR_HS_SEND)
13 Data Valid This bit controls data consistency (see “Data Consistency” on page 63).
1:Output Area valid; exchange data on the sub-network
0:Output Area not valid; do not exchange data on the sub-network
Note: This bit is only relevant if the Control/Status Registers are set as “Enabled”
12 Execute Command If set, the specified command will be executed by the gateway (see below).
11... 8 Control Code This field holds commands which can be executed by the gateway (see below).
