Timing symbol definitions
Oscillator:
f
CLK
= clock frequency
t
CK
= clock period
Timing symbols (acronyms):
Each timing symbol has five characters. The first character
is always a 't' (= time). the remaining four characters of the
symbol (typed in subscript), depending on their relative
positions, indicate the name of a signal or the logical status
of that signal. the designations are as follows:
A =address
C = clock
D = input data
H = logic level HIGH
I = instruction (program memory contents)
L = Logic level LOW or ALE
P = PSEN
Q = output data
R = RD signal
t = time
V = valid
W = WR signal
X = no longer a valid logic level
Z = float
Examples:
t
AVLL
= time for address valid to ALE LOW
t
LLPL
= time for ALE LOW to PSEN LOW
