NEC PD78058F(A) Manuale Utente

The 

µ

PD78056F and 

µ

PD78056FY are Mask ROM with a 49152 x 8 bit configuration, the 

µ

PD78058F and

µ

PD78058FY are Mask ROM with a 61440 x 8 bit configuration and the 

µ

PD78P058F and  

µ

PD78P058FY are PROM

with a 61440 x 8 bit configuration.  They store program and table data, etc.  Normally, they are addressed by the

program counter (PC).

The areas shown below are allocated to the internal program memory space.

The 64-byte area 0000H to 003FH is reserved as a vector table area.  The RESET input and program start

addresses for branch upon generation of each interrupt request are stored in the vector table area.  Of the

16-bit address, low-order 8 bits are stored at even addresses and high-order 8 bits are stored at odd addresses.
