12.12 - XPort 10
The XPort10 is enabled by setting XPEN bit 2 of the SYSCON register and bit 3 of the new XPERCON
register. On the XBUS interface, the register are not bit-addressable. This 16-bit input port can only read
data. There is no output latch and no direction register. Data written to XP10 will be lost.

12.12.1 - Alternate Functions of XPort 10
Each line of XPort 10 is also connected to one of the multiplexer of the Analog/Digital Converter. All port
lines (XP10.15...XP10.0) can accept analog signals (AN31...AN16) that can be converted by the ADC. No
special programming is required for pins that shall be used as analog inputs. The Table 21 summarizes
the alternate functions of XPort 10.
