EEPROM Programming Interface
SAB-C513A-H
9.2 Programming Interface
The programming interface of the SAB-C513A-H allows to erase, write and read the contents of the
EEPROM. In the programming mode the device provides access to the programming interface
registers via the multiplexed address/data bus, which is provided at the port 0 lines. Four lines are
used for controlling of the access to the registers of the programming interface. The programming
interface contains registers which hold the address and data of the EEPROM location(s) to be
accessed and control registers to control the operating modes and the access.
