[ Control ]External Memory Interface Bus in Pic18F

[tienchuan]

Dear all
I've a project interface between PIC18F97J60 and External SRAM HM628128A.
I want to using external memory bus to interface with SRAM.
I read a help in CCS C (ver 4.140) and found some functions to work with it:
- setup_external_memory( )
- write_external_memory( )
- read_external_memory( )

But i don't know clearly how to map pin and port from PIC18F97J60 to SRAM.
Pls give me way to solve it, or give me some tuturial about it.
Thnnks and regards.

The external memory bus uses _fixed_ pinouts. These are in the data sheet.
The only 'configurations', are delays, and the write 'mode' (16bit 8bit etc.), which are setup by 'setup_external_memory'.
Look at register 8-1 in the data sheet, then at the #defines in 18F97J60.h
The 'wait' defines, define the wait bits in this register, and the byte_write, select, and word_write values define the WM bits in this register.

Best Wishes
