8.1 PIO

See the Device Terminal Functions section for the list of supplies to the PIOs (Programmable I/O ports).
PIO lines are configured through software to have either weak or strong pull-ups or pull-downs. All PIO lines are
configured as inputs with weak pull-downs at reset and have additional individual bus-keeper configuration.

8.2 WLAN Coexistence Interface

Dedicated hardware is provided to implement a variety of WLAN coexistence schemes. There is support for:
Channel skipping AFH

Priority signaling

Channel signaling

Host passing of channel instructions

The BT800 supports the WLAN coexistence schemes:
