Operation
Enable SPI Serial Programming after RESET
goes low.
Chip Erase EEPROM and Flash.
Read H (high or low) data o from Program
memory at word address a:b.
Write H (high or low) data i to Program
Memory page at word address b. Data low
byte must be loaded before data high byte is
applied within the same address.
Write Program Memory Page at address a:b.
Read data o from EEPROM memory at
address a:b.
Write data i to EEPROM memory at address
a:b.
Read Lock bits. “0” = programmed, “1” =
unprogrammed. See
286
Write Lock bits. Set bits = “0” to program Lock
bits. See
Read Signature Byte o at address b.
Set bits = “0” to program, “1” to unprogram.
