Touch-Detect Pullup Timing Configuration Register (0x07)
Note: These settings apply to the end of all measurement and combined commands and are required for proper data tagging and
interrupt management. The exception is direct conversion commands with CONT = 1. These commands do not enter PUR/PUF inter-
vals for the purpose of data tagging.
* While 2μs is the minimum PUR interval listed, for this setting, the XPSW is not engaged, allowing for minimal power operation
(essentially adding 2μs to the PUF time).
