Table 3-3: Connector X2 pin assignment
1)
Internally connected to 2.5V. If you want to program the OTP memory, just power this pin with 7.0V.
2)
These IO pins are normally used to access more flash memory. They should not be used as general
purpose IO pins. For more information please see chapter 2.3.
3.4.2 Connector X3 – (61-120)
Please mind the mounted pull up and pull down resistors on the Core Module. See the third column of
Table 3-4.
