input data to be valid within a specific time window relative to the HL-edge of the strobe,
after completion of the strobe’s L-phase.
If necessary, output data as per ha) and hb) can be easily latched with the LH-edge of strobe
DSTBn as they will remain valid for about 0.4 μs beyond as a minimum.
Care must be taken however, that signal delay added by external circuitry is lower for the
strobe than for the data.

Pulse width depends substantially on value of external pull-up resistor
Applies only to data port pins set to 'output / input' operation
Timing reference is DSTBn HL-edge.
Applies only to data port pins set to either 'output / input' or 'input' operation
