The voltage at U5R is derived from the voltage present at UOUT, as long as UOUT is not
switched off due to overload. In the latter case U5R is derived from an alternative voltage out
of the UOUT voltage regulator, which is more or less similar to VUOUT in non switched off
condition of UOUT. As a result VU5R is not affected by overload condition at UOUT and will
remain.

Basically data port D3
, …, D0 is designed for bidirectional data transfer out of and into the
slave device. Each data port pin is equipped with both a low-side open-drain output stage as
well as an input stage to this purpose.
Depending on the so called IO-configuration code, written into and stored in the slave device,
each data port pin is individually set to behave as
output, or
output / input, or
input.
The timing of the data transfer is presented in fig. 2.
Strobe signal DSTBn flags and governs the data transfer as follows:
ha) data port pin is set ‘output’:
output data become valid upon the HL-edge of the strobe and will remain so until the next
HL-edge, hence during the entire strobe cycle;
hb) data port pin is set ‘output / input’:
output data become valid upon the HL-edge of the strobe and will remain so until it’s LH-
edge; input data to be valid within a specific time window relative to the HL-edge, after
completion of the strobe’s L-phase;
hc) data port pin is set ‘input’:
