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. 13.12.1 XPort 10 registers XP10 register XODP9CLR (EB90h) XBus Reset value: 0000h 15 14 13 12 11 10 987 65432 10 XO DP9 CLR .15 XO DP9 CLR .14 XO DP9 CLR .13 XO DP9 CLR .12 XO DP9 CLR .11 XO DP9 CLR .10 XO DP9 CLR .9 XO DP9 CLR .8 XO DP9 CLR .7 XO DP9 CLR .6 XO DP9 CLR .5 XO DP9 CLR .4 XO DP9 CLR .3 XO DP9 CLR .2 XO DP9 CLR .1 XO DP9 CLR .0 WWWWW WWW W WWWWW WW Table 110.
