* Command is illegal but terminal is not using “illegal command detection” (in form response).
** Command is illegal and terminal is using “illegal command detection”
*** Undefined mode command rendered invalid by UMCINV option bit. Command’s bit in Illegalization Table is “don’t care”.
Circumstances for
Received Message
SYNCHRONIZE WITH
DATA WORD (MC17):
Mode code command
with mode code
10001
and T/R bit equals 1
Device stores received data word in the assigned ping-pong or index data buffer (or in Descriptor Word 4 for
SMCP Simplified Mode Command Processing). Configuration Register 2 MCOPT2 and MCOPT3 bits allow
automatic Time-Tag count loading using the data word received. If MCOPT2 equals 1, the received data word
is automatically loaded to the Time-Tag counter if the low order bit of the received data word (bit 0 equals 0. If
MCOPT3 equals 1, the received data word is automatically loaded to the Time-Tag counter if the low order bit of
the received data word (bit 0) equals 1. If both bits are set, the received data word is unconditionally loaded into
the Time-Tag counter. For non-broadcast commands, counter load occurs before status word transmission.
