Here is a project use MPC8280. I use SDRAM machine connect SDRAM(32M16A2).The SDRAM have 4 internal banks, 13 rows, and 10 columns.
I reference 《MPC8280RM Rev. 1, 12/2005》,220.127.116.11 SDRAM Address Multiplexing (SDAM and BSMA),but still have same
The reference book have examples,but all the examples are about SDRAM devices that have 4 internal banks, 12 rows, and 9 columns.
I copy the tables below.
My question is:
what is the meaning "-",is that I cann't use the pin?
for example I set SDMR[SDAM] = 100; Can I use A[14–15] for bank select pins?
