Both the program and data memory arrays can be programmed using the SPI bus while
RESET is pulled to GND. The serial interface consists of pins SCK, MOSI (input) and
MISO (output). See Figure 33. After RESET is set low, the Programming Enable instruc-
tion needs to be executed first before program/erase instructions can be executed.
Figure 33. Serial Programming and Verify
For the EEPROM, an auto-erase cycle is provided within the self-timed write instruction
and there is no need to first execute the Chip Erase instruction. The Chip Erase instruc-
tion turns the content of every memory location in both the program and EEPROM
arrays into $FF.
The program and EEPROM memory arrays have separate address spaces: $0000 to
$01FF for Program memory and $000 to $03F for EEPROM memory.
