• Programming Enable Register
• Programming Command Register
• Flash Data Byte Register
The Reset Register is a Test Data Register used to reset the part during programming.
It is required to reset the part before entering Programming mode.
A high value in the Reset Register corresponds to pulling the external reset low. The
part is reset as long as there is a high value present in the Reset Register. Depending
on the Fuse settings for the clock options, the part will remain reset for a Reset Time-
out period (refer to
The output from this Data Register is not latched, so the reset will take place
immediately, as shown in
The Programming Enable Register is a 16-bit register. The content of this register is
compared to the programming enable signature, binary code 1010_0011_0111_0000.
When the content of the register is equal to the programming enable signature,
programming via the JTAG port is enabled. The register is reset to 0 on Power-on
Reset, and should always be reset when leaving Programming mode.

The Programming Command Register is a 15-bit register. This register is used to
serially shift in programming commands, and to serially shift out the result of the
previous command, if any. The JTAG Programming Instruction Set is shown in
