2.1.11 Illegalization Registers
The 16 registers are divided into 8 blocks, 2 registers per block (see table 1).
Table 1. Illegalization Register Blocks
Block Name
Address (hex)
Receive
0010 and 0011
Transmit
0012 and 0013
Broadcast Receive
0014 and 0015
Broadcast Transmit (Automatically
Illegalized)
0016 and 0017
Mode Code Receive
0018 and 0019
Mode Code Transmit
001A and 001B
Broadcast Mode Code Receive
001C and 001D
Broadcast Mode Code Transmit
001E and 001F
The blocks correspond to the following types of commands. Register address 0010 (hex) and 0011 (hex) illegalize receive commands
to 32 subaddresses. The most significant bit of register 0010 (hex) controls the illegalization of subaddress 01111. The least significant
bit controls subaddress 00000. Register 0011 (hex) controls illegalization of subaddresses 10000 through 11111. The least significant
bit relates to subaddress 10000; the most significant bit relates to subaddress 11111. Transmit commands and broadcast commands
(both receive and transmit) use the same encoding scheme as receive subaddress illegalization.
Registers 18 (hex) through 1F (hex) control the illegalization of mode codes. Register 18 governs the illegalization of receive mode
codes (T/R bit = 0) 00000 through 01111 and register 19 mode codes 10000 through 11111. Register blocks Transmit Mode Code
(T/R bit = 1), Broadcast Receive Mode Codes, and Broadcast Transmit Mode Codes use the same decode scheme as receive mode
codes.
Table 2 shows the illegalization register map. For each block, the numbers shown in the column under each bit number identifies
the specific subaddress or mode code (in hex) that the register bit illegalizes (Logical 0 = legal, Logical 1 = illegal).
