S3F80JB ADDRESS SPACES
2-9
PRIME REGISTER SPACE
The lower 192 bytes of the 256-byte physical internal register file (00H–BFH) are called the prime register space
or, more simply, the prime area. You can access registers in this address using any addressing mode. (In other
words, there is no addressing mode restriction for these registers, as is the case for set 1 and set 2 registers.).
The prime register area on page 0 is immediately addressable following a reset.
