18.8. COEXISTENCE INTERFACE SPECIFICATION
The Coexistence Interface pins are powered from the VIO voltage supply internally connected to
V
DD
= 3.3V. See Chapter 18.3 Digital Pin Characteristics for DC specification.

TxRx Info is valid in BT_STATE on and after T2. The BT_STATE must hold until
there is any change of direction in the next slots.

T4
BT_GRANTn needs to be valid T4 time before the upcoming slot. BT_GRANTn
indicates Tx grant, and may also indicate Rx grant. Once a slot is granted, the
subsequent slots are also granted unless there is a change in direction from Rx to
Tx. Rx to Tx change always re-arbitrates.

T5
TxRx Info for the next slot is valid on and after T5 to the start of the next slot. If
direction remains the same for the next slot, then BT_STATE must not change
during the current slot. If the direction changes for the next slot, the BT_STATE
must change only after the last bit of Bluetooth data is transferred; otherwise the
transfer may be disrupted.

Optional
Priority[1] information is valid in BT_STAT on and after T8. This time parameter only
exists if BCA is configured for 2-bit priority on same BT_STATE pin. Otherwise, the
start of T2 would come after T1.
