If the transceiver is in any active mode (Idle, AUX, TX, RX, RX_Polling), an integrated
debounce logic is active. If there is an event on pin Tn a debounce counter is set to 0
(T = 0) and started. The status is updated, an interrupt is issued and the debounce
counter is stopped after reaching the counter value T = 8195
An event on the same key input before reaching T = 8195
counter. An event on an other key input before reaching T = 8195
restarts the debounce counter.
While the debounce counter is running, the bits VSOUT_EN and CLK_ON in control
register 3 are set to 1.
The interrupt is deleted after reading the status register or executes the command
Delete_IRQ.
If a pin Tn is not used, it can be left open because of an internal pull-up resistor (typically
50 k ).
