2.1.4 C-pin switching
Depending on the microcontroller series SW3-S5/S6 has to be set.
Please refer to the graphic above and to Table 2-4, how to set the C-Pin.
C-Pin Switching
C-Pin exists on V-Chip
P60/70 exist on V-Chip
Please note that 3 Volts V-Chips (e. g. MB90V330) do not have a C pin and SW3-S5 has to
be set to ON and SW3-S6 to OFF. Please see table in chapter 5.1 for device list.
2.1.5 Example settings for MCU-series:
