This must be different from the value held under PSKEY_USB_PRODUCT_ID
.
This value is only used if the chip is presenting its USB interface. See the description of
PSKEY_HOST_INTERFACE
.
Key Name Key Number Type Default Setting
PSKEY_USB_PIO_DETACH 0x02ce uint16 none
The PIO line used for USB detach/attach signalling. Any of the first 8 PIOs (numbered 0-7) may be used.
The absence of this key indicates that this feature is not in use.
This value is only used if the chip is presenting its USB interface. See the description of
PSKEY_HOST_INTERFACE
.
Key Name Key Number Type Default Setting
PSKEY_USB_PIO_WAKEUP 0x02cf uint16 none
The PIO line used for USB wakeup signalling in detach mode. Any of the first 8 PIOs (numbered 0-7) may
be used. The absence of this key indicates that this feature is not in use.
This value is only used if the chip is presenting its USB interface. See the description of
PSKEY_HOST_INTERFACE
.
Key Name Key Number Type Default Setting
PSKEY_USB_PIO_PULLUP 0x02d0 uint16 16
The PIO line used to control the pull-up resistor on the USB D+ line. The absence of this key in the
persistent storage indicates that this feature is not in use.
This value is only used if the chip is presenting its USB interface. See the description of
PSKEY_HOST_INTERFACE
.
On BlueCore, there are 16 PIO lines, 0 to 15 (depending on package type), but 12 to 15 are not available
for the USB pullup. However, an internal pullup can be used by setting this key to 16.
Key Name Key Number Type Default Setting
PSKEY_USB_PIO_VBUS 0x02d1 uint16 none
The PIO line used for USB VBus detection. Any of the first 8 PIOs (numbered 0-7) may be used. The
absence of this key indicates that this feature is not in use.
This value is only used if the chip is presenting its USB interface. See the description of
PSKEY_HOST_INTERFACE
.
Key Name Key Number Type Default Setting
PSKEY_USB_PIO_WAKE_TIMEOUT 0x02d2 uint16 0
The number of seconds for which the PIO wake signal will be asserted following the generation of data that
