#
A “#” symbol following a signal name indicates that the signal is active low. This means that when the signal
is asserted (based on the name of the signal) it is in an electrical low state. Otherwise, signals are driven in
an electrical high state when they are asserted. In state machine diagrams, a signal name in a condition
indicates the condition of that signal being asserted
!
Indicates the condition of that signal not being asserted. For example, the condition “!STPCLK# and HS” is
equivalent to “the active low signal STPCLK# is unasserted (i.e., it is at 1.5 V) and the HS condition is true.”
L
Electrical low signal levels
H
Electrical high signal levels
0
Logical low. For example, BD[3:0] = “1010” = “HLHL” refers to a hexadecimal “A,” and D[3:0]# = “1010” =
“LHLH” also refers to a hexadecimal “A.”
1
Logical high. For example, BD[3:0] = “1010” = “HLHL” refers to a hexadecimal “A,” and D[3:0]# = “1010” =
“LHLH” also refers to a hexadecimal “A.”
