Flash Memory Status
HMS99C51S/52S/54S/56S/58S themselves are delivered in standard with the ISP boot code in the Flash mem-
ory. After ISP or parallel programming, the possible contents of the Flash memory are summarized on Figure 13.
Memory Organization
In the HMS99C51S/52S/54S/56S/58S, the lowest 4K, 8K, 16K, 24K or 32K of the 64 KB program memory ad-
dress space is filled by internal Flash cells. When the EA pin is high, the processor fetches instructions from
internal program Flash memory. Bus expansion for accessing program memory from 4K, 8K, 16K, 24K or 32K
is upward since external instruction fetches occur automatically when the program counter exceeds 0FFFh(4K),
1FFFh(8K), 3FFFh(16K), 5FFFh(24K) or 7FFFh (32K).
If the EA pin is tied low, all program memory fetches are from external memory.
