TiWi-R2 TRANSCEIVER MODULE
DATASHEET
ENABLE SCHEME
The module has 3 enable pins, one for each core: WL_EN, and BT_EN and FM_EN. Presently, there are 2
modes of active operation now supported: WLAN and Bluetooth. It is recommended that the FM_EN pin be
grounded to disable the FM section. It is also recommended that the FM section be disabled by Bluetooth HCI
commands.
1. Each core is operated independently by asserting each signal EN to Logic '1’. I n this mode it is possible to
control each core asynchronously and independently.
2. Bluetooth mode operation. WLAN will be operated through WL_EN asynchronously and independently of
Bluetooth.
IRQ OPERATION
1. The default state of the WLAN_IRQ prior to firmware initialization is 0.
2. During firmware initialization, the WLAN_IRQ is configured by the SDIO module; a WLAN_IRQ changes
its state to 1.
3. A WLAN firmware interrupt is handled as follows:
a. The WLAN firmware creates an Interrupt-to-Host, indicated by a 1-to-0 transition on the
WLAN_IRQ line (host must be configured as active-low or falling-edge detect).
b. After the host is available, depending on the interrupt priority and other host tasks, it masks the
firmware interrupt. The WLAN_IRQ line returns to 1 (0-to-1 transition on the WLAN_IRQ line).
c.
The host reads the internal register status to determine the interrupt sources - the register is
cleared after the read.
d. The host processes in sequence all the interrupts read from this register
e. The host unmasks the firmware interrupts.
4. The host is ready to receive another interrupt from the WLAN device.
The information in this document is subject to change without notice.
