ADVANCE INFORMATION
Hex
Unless otherwise noted, write 0FFH to reserved memory locations and write 0 to reserved SFR bits.
The contents or functions of reserved locations may change in future device revisions, in which case a
program that relies on one or more of these locations might not function properly.
External memory if EA# is low; internal ROM if EA# is high.
External device (memory or I/O) connected to address/data bus
