9.4.2 Read mode
At the falling edge of signal WRITE_READ the bus interface is set to the read mode. Data
is clocked out on every falling edge of the input clock. In the read mode, pin DATA
becomes an open-collector output and an external pull-up resistor is required.
9.4.3 Dbus function in 3-wire mode (silent readout)
Bus pins CLOCK and DATA are bidirectional and act as inputs when bit DBUS = 0, but are
open-collector outputs when bit DBUS = 1. External pull-up resistors are required in this
case.
In Dbus mode, pins CLOCK and DATA are used for output data and pin WRITE_READ is
used as an input.
With a rising edge (write mode) or falling edge (read mode) of signal WRITE_READ the
Dbus mode is deactivated and a transmission is started.
The Dbus mode is activated with bit DBUS = 1 and after transfer of all 6 data bytes in the
write mode or all 3 data bytes in the read mode.
Data on pins CLOCK and DATA in the Dbus mode is given in Table 8.
