Input signals to the processor are represented using dashed waveforms.
Outputs and bidirectional signals are represented using solid waveforms.
Fixed parameters are shown using double arrows in grey (black and white print) or green
(color print).
Programmable parameters are shown using bold single arrows.
The processor register that is used to change a specific timing is given in the corresponding
timing table.
