/****************************************************************************
**
** Name: MT2063_SetReg
**
** Description: Sets an MT2063 register.
**
** Parameters: h - Tuner handle (returned by MT2063_Open)
** reg - MT2063 register/subaddress location
** val - MT2063 register/subaddress value
**
** Returns: status:
** MT_OK - No errors
** MT_COMM_ERR - Serial bus communications error
** MT_INV_HANDLE - Invalid tuner handle
** MT_ARG_RANGE - Argument out of range
**
** Dependencies: USERS MUST CALL MT2063_Open() FIRST!
**
** Use this function if you need to override a default
** register value
