2. The serial number is only supported in the external configuration map and not in the four internal configuration maps.
The general purpose pins (GP0 to GP5)
The UDA1321 has 6 General Purpose (GP) pins; these are pins GP0 to GP5. These can be used either for digital I/O
functions or for general purposes. The configurations presented are as implemented in the standard firmware.
There are basically three port configurations:
These port configurations can be selected via the configuration map at start-up of the UDA1321.
The user can make a selection between two functions for each of the pins GP0 to GP4 (see byte 5 in Table 6), except if
digital I/O communication is selected (see Tables 7, 8 and 9).
