PIC18F87J11 FAMILY
8.0
EXTERNAL MEMORY BUS
The External Memory Bus allows the device to access
external memory devices (such as Flash, EPROM,
SRAM, etc.) as program or data memory. It supports
both 8 and 16-Bit Data Width modes and three address
widths of up to 20 bits.
The bus is implemented with 28 pins, multiplexed
across four I/O ports. Three ports (PORTD, PORTE
and PORTH) are multiplexed with the address/data bus
for a total of 20 available lines, while PORTJ is
multiplexed with the bus control signals.
A list of the pins and their functions is provided in
TABLE 8-1:
PIC18F87J11 FAMILY EXTERNAL BUS – I/O PORT FUNCTIONS
Note:
The External Memory Bus (EMB) is not
implemented on 64-pin devices.
