4.8. Data Port and DSTBn
4.8.1.
Every data pin (D0…D3) contains an NMOS open drain output driver as well as a high voltage high
impedance input stage. Received output data is stored at the Data Output Register and subsequently
forwarded to the data pins. A certain time (t
is sampled.
The availability of new output data is signaled by the Data Strobe (DSTBn) signal as shown in Figure 7. The
DSTBn pin has an additional reset input function, which is described further in chapter 4.13 IC Reset.
Any IC reset turns the Data Output Register to 0xF and forces the data output drivers to high impedance state.
Simultaneously, a Data Strobe is generated, having the same t
output data would be driven.
