13.2.6.1 Test Pin

One dedicated pin, TST, is used to define the device operating mode. When this pin is at low level during power-up, the device is in normal operating mode. When at high level, the device is in Test mode or FFPI mode. The TST pin integrates a permanent pull-down resistor of about 15 kΩ, so that it can be left unconnected for normal operation. Note that when setting the TST pin to low or high level at power-up, the pin must remain in the same state for the duration of the operation.
