Master reset
When the device's reset is held active (nreset is low), uart1_txd and uart2_txd are set to
input state. When the nreset returns high, the device starts to boot.
The device should be held in active reset for minimum 20ms in order to guarantee a
complete reset of the device.
Interrupts/wake-up
All GPIOs can be used both as external interrupt source and as wake-up source. In addition
the device can be woken-up by USB, uart1_rxd, uart2_rxd, int1, int2.
V1.2 detailed functionality - Extended SCO
This function gives improved voice quality since it enables the possibility to retransmit lost or
corrupted voice packets in both directions.
eSCO incorporates CRC, negotiable data rate, negotiable retransmission window and multi-
slot packets. Retransmission of lost or corrupted packets during the retransmission window
guarantees on-time delivery.

V1.2 detailed functionality - Adaptive frequency hopping
In the Bluetooth spec 1.1 the Bluetooth devices hop in the 2.4 GHz band over 79-channels.
Since WLAN 802.11 has become popular, there are specification improvements in the 1.2-
SIG spec for Bluetooth where the Bluetooth units can avoid the jammed bands and thereby
provide an improved co-existence with WLAN.
