FPACKAGE-100
For 100-pin packages, when the FPACKAGE bit is set to 100 pins, GPIO PA18, PA19, and PA20 are disabled for TQFP100 parts.
Workaround
Set the FPACKAGE bit to 144 pin to enable PA18, PA19, and PA20. This configures the TQFP100 package to behave as a 144-pin package. Therefore, some ports that are not bonded out will be enabled.
