The processor supports 111 different opcodes and references both a 64K program address space and a 64K data storage space. RAM The internal data RAM in the W78LE516 is 512 bytes. It is divided into two banks: 256 bytes of scratchpad RAM and 256 bytes of AUX-RAM. These RAMs are addressed by different ways. • RAM 0H−7FH can be addressed directly and indirectly as the same as in 8051. Address pointers are R0 and R1 of the selected register bank. |
