NOTES:
H = High-voltage level
h = High state must be present one setup time before the low-to-high clock transition
L = Low-voltage level
l = Low state must be present one setup time before the low-to-high clock transition
NC= No change
X = Don’t care
Z = High impedance “off” state
↑ = Low-to-high clock transition
↑ = Not low-to-high clock transition
OPERATING MODE
Load and read register
Hold
