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:
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.
PASSIV: no input function and open drain output is fixed at high-impedance state
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 33.

1 Slaves running in Extended_Address_Mode (ID_Code = 0xA) will output the respective select bit (I3) at the
P3 pin and at the D3 pin in case it is configured as OUT or I/O.
2 The special case IO_Code = 0x7 causes the Parameter Ports acting as Data Inputs after DEXG master
calls. Thus a bi-directional data exchange with separate data inputs and outputs is possible. Parameter Ports
are always outputs after WPAR master calls.
NOTE: IO_Code = 0x7 is not allowed for the SAP5 16 Pin version.
3 There is no data exchange possible in case IO_Code = 0xF, i.e. Data Outputs are always at high impedance
state, no slave answer is generated for received DEXG master calls.
