To read from the AR, the address must be previously latched by writing it to address 1FFh
with DWB set to “0.” Bits 0–7 have no meaning. Because the bits are not going to be
written in this mode, only the port number is latched.
At least one cycle delay (NOP) is required between two consecutive accesses to the AR. If
access is performed by a two-cycle instruction, no delay is necessary.
External memory must exhibit access times of less than 60 ns. Table 5 lists the additional
control registers.
