MikroElektronika
11.0. Serial RAM
Thanks to the built-in 23K640 circuit, the development system has 64Kbit RAM memory that can be connected to the microcontroller
via SPI serial connection. SPI serial communication is enabled by means of DIP switch SW11. Switches 7 and 8 on the DIP switch
SW11 enable RAM-CS and RAM-HOLD. RAM-CS is used for controlling the access to RAM memory, whereas RAM-HOLD is used to
temporarily disable communication between the microcontroller and RAM.

12.0. Serial EEPROM
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a built-in memory module used to store data that must be
saved when power goes off. The 24AA01 circuit is capable of storing up to 1Kbit data. It communicates to the microcontroller via
RC4, RB4, RC3 and RB6 pins by means of serial I
microcontroller, it is necessary to set switches 1 and 3 on the DIP switch SW13 to the ON position. Switches 2 and 4 can also be used
for this purpose depending on which pins are to be used for serial communication.
