1.3 Functional
Restrictions
1.3.1 Valid for EMA-MB91V460A-002B/-80/003
This probe cable can only be used for the following Microcontroller configuration:
1. VDD5 = 5V, VDD35 = 3.3V
The following Microcontroller configurations (2 & 3) are applicable with this probe cable, but
it is recommended to use the appropriate MCU “NLS” probe cable!
2. VDD5 = 5V, VDD35 = 5V
3. VDD5 = 3.3V, VDD35 = 3.3V
While using this probe cable, the GPIO functionality on the external bus interface (VDD35
voltage domain) is restricted!
Unused external bus function pins (e.g. address lines) cannot be configured as general
purpose in- or output randomly!
The following ports can be configured as permanent general purpose input OR output.
1. P07[0..7]
2. P06[0..7]
3. P05[0..7]
It is only possible to configure the whole port as input OR output!
Configuring each pin of these ports separately as input or output is not applicable!
For details on how to configure the port input and output direction please see chapter 3.2
Level-shifter direction control jumper!
The following pins can be configured as permanent general purpose input OR output
separately.
4. P08[0..1], P08_4, P08_7, P09[0..3], P10[0..1], P10_3
It is possible to configure the pins each as input OR output! Configuring each pin of these
ports separately as input or output is applicable by removing certain resistors and making
appropriate DIP-Switch settings!
For details on how to configure the pins input and output direction please see chapter 3.3
Bus control jumpers and the corresponding schematics.
APIX functionality must be emulated via external bus access to extension board EMA-
MB91V460A-300. Please refer also to chapter “Port 17 Jumpers (APIX AIC Link)” for further
restrictions.
