Byte 1
Programming through the JTAG interface requires control of the four JTAG specific pins: TCK,
TMS, TDI, and TDO. Control of the reset and clock pins is not required.
To be able to use the JTAG interface, the JTAGEN Fuse must be programmed. The device is
default shipped with the fuse programmed. In addition, the JTD bit in MCUCR must be cleared.
Alternatively, if the JTD bit is set, the external reset can be forced low. Then, the JTD bit will be
cleared after two chip clocks, and the JTAG pins are available for programming. This provides a
means of using the JTAG pins as normal port pins in Running mode while still allowing In-Sys-
tem Programming via the JTAG interface. Note that this technique can not be used when using

Operation
Load data i to EEPROM memory page buffer. After
data is loaded, program EEPROM page.
Read Lock bits. “0”=programmed, “1”=unprogrammed.
See
Write Lock bits. Set bits = “0” to program Lock bits.
See
Set bits = “0” to program, “1” to unprogram.
See
Set bits = “0” to program, “1” to unprogram.
See
Set bits = “0” to program, “1” to unprogram.
See
Read Fuse bits. “0”=programmed, “1”=unprogrammed.
See
Read Fuse High bits.
“0”=programmed, “1”=unprogrammed.
See
Read Extended Fuse bits.
“0”=programmed, “1”=unprogrammed.
See
If o = “1”, a programming operation is still busy. Wait
until this bit returns to “0” before applying another
command.
