pin 44, the system will run into a parallel mode
(MUX_MODE = L)
(MUX_MODE = H). It is not possible to change the logic
state once the system is running.
the internal pull up resistors (I/O_A and I/O_B line) will be
either connected to ANLG_VCC voltage (EN_RPU = H) or
disconnected (EN_RPU = L). It is not possible to change this
operating condition once the system is running.
