BU-63825
C-02/06-0
External Time Tag Clock input. Use may be designated by bits 7, 8, and 9 of Configuration Register #2. When used it
increments the internal Time Tag Register/Counter. If not used, should be connected to +5V or ground.
63
TAG_CLK (I)
Subsystem Flag or External Trigger input. In the Remote Terminal mode, asserting this input will set the Subsystem Flag
bit in the BU-63825’s RT Status Word. A low on the SSFLAG input overrides a logic “1” of the respective bit (bit 8) of
Configuration Register #1. In the Bus Controller mode, an enabled external BC Start option (bit 7 of Configuration
Register #1) and a low-to-high transition on this input will issue a BC Start command, starting execution of the current
BC frame. In the Word Monitor mode, an enabled external trigger (bit 7 of Configuration Register #1) and a low-to-high
transition on this input will issue a monitor trigger.
27
SSFLAG (I)/
EXT_TRIG (I)
In Command. In BC mode, asserted low throughout processing cycle for each message. In RT mode or Message
Monitor mode, asserted low following receipt of Command Word and kept low until completion of current message
sequence. In Word Monitor mode, goes low following MONITOR START command, kept low while monitor is on-line,
goes high following RESET command.
45
INCMD (O)
Master Clear. Negative true Reset input, normally asserted low following power turn-on. Requires a minimum 100ns neg-
ative pulse to reset all internal logic to its “power turn-on” state.
7
MSTCLR (I)
16MHz (or 12MHz) clock input.
