Block description
– PROCU Memories
Two types of memory is used: DRAM, and FLASH (ROM). The E3G CPU
has a 22 bits (26 bit internal) wide external address bus A(21:0) and an
16–bit data bus. The address bits A(25:11) are used for chip select
decoding. The decoding is done internally on the E3G CPU.
PROCU memory map is illustrated in figures 1 and 2 and in Table 31
DRAM (70 ns) is refreshed only when main battery is connected. As long
as the main battery has power and is connected all the DRAM data stays
valid. When the main battery is removed all the DRAM data is lost.
All application data is saved to nonvolatile FLASH memory under control
of flash file system (TFFS by M–Systems). Application status is not stored.
