Notes
1. The TC output is HIGH when CET is HIGH and the counter is at terminal count (HHHH).
H = HIGH voltage level
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH CP transition
L = LOW voltage level
I = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition
q = lower case letters indicate the state of the referenced output one set-up time prior to the
LOW-to-HIGH CP transition
X = don’t care
↑ = LOW-to-HIGH CP transition
