SFRs (80H to FFH)
: direct addressing
4 register banks (00H to 1FH)
: direct addressing; only 1 register bank may be
enabled at any time
Bit-addressable locations (20H to 2FH)
: direct addressing; these 16 bytes can
be used as 128 bit-addressable locations.
10.2.2
Program memory
The ISP1130 has 8 kbytes of masked ROM for storing the 80C51 operating software.
In order to protect the ROM against illegal copying, execution of a MOVC instruction
from external code memory has been blocked. Instead of reading the program
memory, it accesses the on-chip data memory.
10.3 Special function registers (SFRs)
The SFRs of the 80C51 can only be directly addressed. The memory map is given in
Table 47
