MEMORY ORGANIZATION
FM8P51 series memory is organized into program memory and data memory.
1.1 Program Memory Organization
The FM8P51 series have an 12-bit Program Counter capable of addressing a 4K×13 program memory space.
The RESET vector for the FM8P51 series is at FFFh.
The H/W interrupt vector is at 001h. And the S/W interrupt vector is at 002h.
FM8P51 series has program memory size greater than 1K words, but the CALL and GOTO instructions only have a
10-bit address range. This 10-bit address range allows a branch within a 1K program memory page size. To allow
CALL and GOTO instructions to address the entire 4K program memory address range for FM8P51 series, there is
another two bits to specify the program memory page. This paging bit comes from the PG<1:0> bits (STATUS<6:5>).
When doing a CALL or GOTO instruction, the user must ensure that page bit PG<1:0> are programmed so that the
desired program memory page is addressed. When one of the return instructions is executed, the entire 12-bit PC is
POPed from the stack. Therefore, manipulation of the PG <1:0> is not required for the return instructions.
