XPort 10

XPort 10 is enabled by setting the XPEN and XPORT10EN/XPORT9EN bits of the

SYSCON and XPERCON registers respectively. 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 are lost.
