Port K general purpose input/output data—Data Register
Port K pins 7 through 0 are associated with external bus control signals and internal memory expansion emulation
pins. These include ADDR[22:16], Access Source (ACC[2:0]), External Wait (EWAIT) and instruction pipe signals
IQSTAT[3:0]. Bits 6-0 carry the external addresses in all expanded modes. In emulation modes the address is
multiplexed with the alternate functions ACC and IQSTAT on the respective pins.
When not used with the alternative function, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
