242/*================== Module Overview =====================================
243<verbatim>
244The BTHD (Broadcom Terrestrial Handheld Demodulator) portinginterface (PI)
245controls the RF front-end block on any Broadcom chip that has one or more
246DVB T/H core(s), such as BCM2940. The BTHD PI is responsible for controlling
247the terrestrial tuner, and theterrestrial downstream receiver.
248
249The BTHD PI device is accessed by the handle BTHD_Handle. There is 1
250BTHD_Handle per Broadcom chip. A BTHD_Handle will have 1 or more channels,
251depending on the number of THD cores present in the Broadcom chip.
252
253The BTHD_Handle shall be proveded the following API
254    BTHD_Open
255    BTHD_Close
256    BTHD_Init
257    BTHD_TuneAcquire
258    BTHD_GetVersion
259    BTHD_GetThdStatus
260    BTHD_ResetInbandStatus
261    BTHD_GetInterruptEventHandler
262    BTHD_HandleInterrupt_isr
263
264The magnum/portinginterface/THD/bthd.h header file defines a standard THDT/H
265front-end API for all Broadcom THD chips.  The implementation of the API for
266each chip is in the magnum/portinginterface/thd/<chip> directory. 
267
268Interrupt Requirements
269The application needs to call BTHD_HandleInterrupt_isr() when it receives
270the THDT L1 interrupt.
271
272Sample Code
