Figure 14 summarizes the 16 Illegalization Table loca-
tions for mode commands. These locations are scat-
tered throughout the overall Illegalization Table shown in
Figure 13. Remember: the host must initialize all table
locations corresponding to both subaddress 0 and sub-
address 31 (11111 binary).
Consider an example in which all reserved and all unde-
fined mode commands are illegal. If all defined transmit
mode commands are legal except MC0 (”dynamic bus
control”) the eight table entries for transmit mode com-
mands would be:
0x01FF and 0x01C1 = 1111 1111 1111 0010 = 0xFFF2
0x01FE and 0x01C0 = 1111 1110 0000 0001 = 0xFE01
0x017F and 0x0141 = 1111 1111 1111 1111 = 0xFFFF
0x017E and 0x0140 = 1111 1110 0000 0101 = 0xFE05
The receive mode command words are encoded simi-
larly. Continuing the same example where all reserved
