Meaning
Change the value of the signal from the logically False state to the
logically True state. For active High signals, the asserted signal
value is 1 (High); for active Low signals, the asserted signal value is
0 (Low). The active polarity (High or Low) is defined by the signal
name (see SIGNAL and SIGNAL below).
Change the value of the signal from the logically True state to the
logically False state.
Signal names are in uppercase and in the Courier font. An overbar
on a signal name indicates that it is active Low. To assert SIGNAL is
to drive it Low; to deassert SIGNAL is to drive it High.
Signal names are in uppercase and in the Courier font. An active
High signal has no overbar. To assert SIGNAL is to drive it High; to
deassert SIGNAL is to drive it Low.
An uppercase X indicates any of several values is allowed, where X
can be any legal pattern. For example, a binary value of 0X00 can be
either 0100 or 0000, a hex value of 0xX is 0x0 or 0x1, and so on.
Hexadecimal numbers have a prefix of 0x. For example, 0x00FF is
the hexadecimal number FF. Binary numbers are indicated with a b
suffix, for example, 1011b. Decimal numbers are written without a
prefix or suffix.
