Memory
Following features are provided for memory access (SRAM or FEPROM) :
– 16 bit databus and 20 bit address bus giving 1Mbyte address space per chip select
– control signals : E_nCS[0:1], E_nOE, E_nWE0, E_nWE1
– setup and wait state insertion
– 8, 16 and 32 bit access by MTC20136 to 8 or 16 bit memory according to little endian convention
