Description
1,2,3,4
This pin can be configured by software to
be any of the following
•
LP_WAKEUP_IN :This is LP
Powersave Wakeup indication to
Device from HOST
•
HOST_WAKEUP_INDICATION : This
is used as indication from Host to dev
that host is ready to take the packet
and Device can transfer the packet to
host. This is supported only in UART
host mode.
The UART interface is supported only
in WiSeConnect™.
ULP_GPIO_6

Default :
HighZ
Sleep
: HighZ
This pin can be configured by software to
be any of the following
•
WAKEUP_FROM_Dev - Used as a
wakeup indication to host from device
•
BT_PRIORITY**: Active-high signal
from an external Bluetooth IC that
indicates that the Bluetooth
transmissions are a higher priority.
*For Wake-on-Wireless, it is
recommended to use an external weak
pull-down or pull-up resistor. It is
recommended to use weak pull-down
resistor in new designs. Software has to
be configured suitably for using either pull-
down or pull-up resistor.
**This pin is intended to act as
BT_PRIORITY for Bluetooth coexistence.
