invalid) option bit in Configuration Register1. If UMCINV is asserted, there is no recognition of the undefined com-
mand by the terminal. If UMCINV is zero, the commands are considered valid. Terminal response when UMCINV
equals 0 is wholly determined by the Illegalization Table:
a. If a command’s bit in the Illegalization Table equals zero, the terminal responds “in form” with Clear Status.
b. If a command’s bit in the Illegalization Table equals one, the command is considered illegal. The Message
(b) above, the terminal illegalizes any reserved mode command having Illegalization Table bit equal to 1, and re-
sponds “in form” when the Table bit equals zero. The “in form” response for reserved mode commands 16 through
31 transacts a received or transmitted data word.

Mode commands 17, 20 and 21 are undefined when T/R bit equals one, but will transmit a contiguous data
word. Mode commands 16, 18 or 19 are undefined when T/R bit equals 0, but will receive a contiguous data
word.
Error (ME) status bit is asserted and the terminal transmits status without data word. Illegal mode commands
16-31 will not transmit or receive a mode data word.
