TPISR – Tiny Programming Interface Status Register
Table 18-13. Guard Time Settings
The default Guard Time is 128 IDLE bits. To speed up the communication, the Guard Time
should be set to the shortest safe value.
• Bits 7:2, 0 – Res: Reserved Bits
These bits are reserved and will always read as zero.
• Bit 1 – NVMEN: Non-Volatile Memory Programming Enabled
NVM programming is enabled when this bit is set. The external programmer can poll this bit to
verify the interface has been successfully enabled.
NVM programming is disabled by writing this bit to zero.
