4.9. Data and Parameter Port Configuration
Data and Parameter ports are configured by programming the IO_Code in the E²PROM. Moreover, the
configuration also depends on the Safety_Mode_Enable settings.
NOTE: Below Table 25 refers to slaves not running in Safety Mode (refer to chapter 4.18)
The following configurations are possible:
If one of the data ports D0…D3 is configured as OUT, the SAP5 slave answer to a DEXG master request
contains the respective information bit I0...I3 received from the master. However, parameter ports P0...P3 are
always operated bi-directional, including a read-back of the actual port level as described in chapter 4.8 on
page 34.

state, no slave answer is generated for received DEXG master calls.
There is no data exchange possible in case IO_Code = 0xF, i.e. Data Outputs are always at high impedance
Slaves running in Extended_Address_Mode (ID_Code = 0xA) will output the respective select bit (I3) at the
The special case IO_Code = 0x7 causes the Parameter Ports acting as Data Inputs after DEXG master

OUT: output only, data are valid up to the next DSTBn/PSTBn strobe pulse
IN: input only, open drain output is fixed at high-impedance state
I/O: bi-directional port with timing according to Figure 6 and Figure 7
INOUT: In case IO_Code = 7 Parameter ports are configured outputs after WPAR master calls and
inputs after DEXG master calls, respectively.
