Register Descriptions

EEPROM

There is an EEPROM on the Breadboard for identification. The offset of it
is FE

in A24 address space. The size of the EEPROM is 64 words (128

byte) and all the characteristics of M-Module are stored in it. The first 16
words (0 through 15) are defined in the M-Module Specifications; words 16
- 63 are described in Table 3-4.
