Hi,

I am using upsd3234.

I want to interface 32K SRAM M48T35Y to upsd3234.

My interface is like this: PA0 - PA7 of upsd3234 to D0 - D7 of M48T35Y.

AD0 - AD7 of upsd3234 to A0 - A7 of M48T35Y.

A8 - A11 of upsd3234 to A8 - A11 of M48T35Y.

/RD, /WR to directly connect to M48T35Y.

My question is how memory mapping and paging is structured ?

Thank you.
