bus, the data located in this ROM is only accessible by the first read of a single read instruction or the first read
of a dual parallel read instruction. Therefore, during development using the RAM based part, the data to be
mapped in the on-chip XROM on the ROM based part should not be accessed with a second read during a
dual parallel read instruction.
