The TPI is accessed via three pins, as follows:
In addition, the V
device. See
Figure 14-2. Using an External Programmer for In-System Programming via TPI
NVM can be programmed at 5V, only. In some designs it may be necessary to protect compo-
nents that can not tolerate 5V with, for example, series resistors.
The following sequence enables the Tiny Programming Interface (see

• Apply 5V between V
• Depending on the method of reset to be used:
• Wait t
• Keep the TPIDATA pin high for 16 TPICLK cycles
– Either: wait t
– Or: if the RSTDISBL configuration bit has been programmed, apply 12V to the

This will reset the device and enable the TPI physical layer. The RESET pin must
then be kept low for the entire programming session
